pub const fn align_of<T>() -> usize🔬This is a nightly-only experimental API. (
core_intrinsics)This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).
Expand description
The minimum alignment of a type.
Note that, unlike most intrinsics, this is safe to call;
it does not require an unsafe block.
Therefore, implementations must not require the user to uphold
any safety invariants.
Note that, unlike most intrinsics, this can only be called at compile-time
as backends do not have an implementation for it. The only caller (its
stable counterpart) wraps this intrinsic call in a const block so that
backends only see an evaluated constant.
The stabilized version of this intrinsic is core::mem::align_of.
