pub const MIN: Self = 0
The smallest value that can be represented by this integer type.

1.0.0 (const: 1.32.0) ยท Sourcepub const fn count_ones(self) -> u32
This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
pub const fn count_ones(self) -> u32
Returns the number of ones in the binary representation of self.
ยงExamples
1.0.0 (const: 1.32.0) ยท Sourcepub const fn count_zeros(self) -> u32
This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
pub const fn count_zeros(self) -> u32
Returns the number of zeros in the binary representation of self.
ยงExamples
let zero = 0u16;
assert_eq!(zero.count_zeros(), 16);
let max = u16::MAX;
assert_eq!(max.count_zeros(), 0);This is heavily dependent on the width of the type, and thus might give surprising results depending on type inference:
let lucky = 7;
foo(lucky);
assert_eq!(lucky.count_zeros(), 5);
assert_eq!(lucky.count_ones(), 3);
let lucky = 7;
bar(lucky);
assert_eq!(lucky.count_zeros(), 13);
assert_eq!(lucky.count_ones(), 3);You might want to use Self::count_ones instead, or emphasize
the type youโre using in the call rather than method syntax:

pub const fn rotate_left(self, n: u32) -> Self
Shifts the bits to the left by a specified amount, n,
wrapping the truncated bits to the end of the resulting integer.
rotate_left(n) is equivalent to applying rotate_left(1) a total of n times. In

Sourcepub const fn funnel_shl(self, rhs: Self, n: u32) -> Self
๐ฌThis is a nightly-only experimental API. (funnel_shifts #145686)
pub const fn funnel_shl(self, rhs: Self, n: u32) -> Self
funnel_shifts #145686)Performs a left funnel shift (concatenates self with rhs, with self
making up the most significant half, then shifts the combined value left
by n, and most significant half is extracted to produce the result).
Please note this isnโt the same operation as the << shifting operator or
rotate_left, although a.funnel_shl(a, n) is equivalent
to a.rotate_left(n).
ยงPanics
If n is greater than or equal to the number of bits in self
ยงExamples
Basic usage:

pub const fn funnel_shr(self, rhs: Self, n: u32) -> Self
funnel_shifts #145686)Performs a right funnel shift (concatenates self and rhs, with self
making up the most significant half, then shifts the combined value right
by n, and least significant half is extracted to produce the result).
Please note this isnโt the same operation as the >> shifting operator or
rotate_right, although a.funnel_shr(a, n) is equivalent

๐ฌThis is a nightly-only experimental API. (funnel_shifts #145686)

Sourcepub const fn carryless_mul(self, rhs: Self) -> Self
๐ฌThis is a nightly-only experimental API. (uint_carryless_mul #152080)
pub const fn carryless_mul(self, rhs: Self) -> Self
uint_carryless_mul #152080)Performs a carry-less multiplication, returning the lower bits.
This operation is similar to long multiplication in base 2, except that exclusive or is used instead of addition. The implementation is equivalent to:
pub fn carryless_mul(lhs: u16, rhs: u16) -> u16{
let mut retval = 0;
for i in 0..u16::BITS {
if (rhs >> i) & 1 != 0 {
// long multiplication would use +=
retval ^= lhs << i;
}
}
retval
}The actual implementation is more efficient, and on some platforms lowers directly to a dedicated instruction.
ยงUses
Carryless multiplication can be used to turn a bitmask of quote characters into a bit mask of characters surrounded by quotes:
r#"abc xxx "foobar" zzz "a"!"#; // input string
0b0000000010000001000001010; // quote_mask
0b0000000001111110000000100; // quote_mask.carryless_mul(!0) & !quote_maskAnother use is in cryptography, where carryless multiplication allows for efficient
implementations of polynomial multiplication in GF(2)[X], the polynomial ring
over GF(2).

pub const unsafe fn unchecked_add(self, rhs: Self) -> Self
Unchecked integer addition. Computes self + rhs, assuming overflow
cannot occur.
Calling x.unchecked_add(y) is semantically equivalent to calling
x.checked_add(y).unwrap_unchecked().
If youโre just trying to avoid the panic in debug mode, then do not
use this. Instead, youโre looking for wrapping_add.
ยงSafety
This results in undefined behavior when

Unchecked integer subtraction. Computes self - rhs, assuming overflow

Calling x.unchecked_sub(y) is semantically equivalent to calling

If youโre just trying to avoid the panic in debug mode, then do not
use this. Instead, youโre looking for wrapping_sub.
If you find yourself writing code like this:
if foo >= bar {
// SAFETY: just checked it will not overflow

// ... use diff ...
}Consider changing it to
As that does exactly the same thing โ including telling the optimizer
that the subtraction cannot overflow โ but avoids needing unsafe.

๐ฌThis is a nightly-only experimental API. (disjoint_bitor #135758)
pub const unsafe fn unchecked_disjoint_bitor(self, other: Self) -> Self
disjoint_bitor #135758)Same value as self | other, but UB if any bit position is set in both inputs.
This is a situational micro-optimization for places where youโd rather
use addition on some platforms and bitwise or on other platforms, based
on exactly which instructions combine better with whatever else youโre
doing. Note that thereโs no reason to bother using this for places
where itโs clear from the operations involved that they canโt overlap.
For example, if youโre combining u16s into a u32 with
((a as u32) << 16) | (b as u32), thatโs fine, as the backend will
know those sides of the | are disjoint without needing help.
ยงExamples

// SAFETY: `1` and `4` have no bits in common.
unsafe {
assert_eq!(1_u16.unchecked_disjoint_bitor(4), 5);
}ยงSafety
Requires that (self & other) == 0, otherwise itโs immediate UB.

pub const fn wrapping_neg(self) -> Self
Wrapping (modular) negation. Computes -self,

Since unsigned types do not have negative equivalents
all applications of this function will wrap (except for -0).
For values smaller than the corresponding signed typeโs maximum
the result is the same as casting the corresponding signed value.

MAX is the corresponding signed typeโs maximum.

This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
pub const fn wrapping_shl(self, rhs: u32) -> Self
Panic-free bitwise shift-left; yields self << mask(rhs),
where mask removes any high-order bits of rhs that
would cause the shift to exceed the bitwidth of the type.
Beware that, unlike most other wrapping_* methods on integers, this
does not give the same result as doing the shift in infinite precision
then truncating as needed. The behaviour matches what shift instructions
do on many processors, and is what the << operator does when overflow
checks are disabled, but numerically itโs weird. Consider, instead,
using Self::unbounded_shl which has nicer behaviour.
Note that this is not the same as a rotate-left; the
RHS of a wrapping shift-left is restricted to the range
of the type, rather than the bits shifted out of the LHS
being returned to the other end. The primitive integer
types all implement a rotate_left function,
which may be what you want instead.

This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
pub fn carrying_mul(self, rhs: Self, carry: Self) -> (Self, Self)
Calculates the โfull multiplicationโ self * rhs + carry
without the possibility to overflow.
This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.
Performs โlong multiplicationโ which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create โbig integersโ which represent larger values.
If you also need to add a value, then use Self::carrying_mul_add.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.
This cannot overflow, as the double-width result has exactly enough space for the largest possible result. This is equivalent to how, in decimal, 9 ร 9 + 9 + 9 = 81 + 18 = 99 = 9ร10โฐ + 9ร10ยน = 10ยฒ - 1.

pub const fn from_ascii_radix( src: &[u8], radix: u32, ) -> Result<u16, ParseIntError>
int_from_ascii #134821)Parses an integer from an ASCII-byte slice with digits in a given base.
The characters are expected to be an optional
+
sign followed by only digits. Leading and trailing non-digit characters (including
whitespace) represent an error. Underscores (which are accepted in Rust literals)
also represent an error.
Digits are a subset of these characters, depending on radix:
0-9a-zA-Z
ยงPanics
This function panics if radix is not in the range from 2 to 36.
ยงExamples
Trailing space returns error:

fn from_str(src: &str) -> Result<u16, ParseIntError>
Parses an integer from a string slice with decimal digits.
The characters are expected to be an optional
+
sign followed by only digits. Leading and trailing non-digit characters (including
whitespace) represent an error. Underscores (which are accepted in Rust literals)
also represent an error.

see from_str_radix.
