Module fmt 

Utilities for formatting and printing strings.

Structs

Argumentsvalidated

This structure represents a safely precompiled version of a format string and its arguments. This cannot be generated at runtime because it cannot safely be done, so no constructors are given and the fields are private to prevent modification.

DebugListvalidated

A struct to help with fmt::Debug implementations.

DebugMapvalidated

A struct to help with fmt::Debug implementations.

DebugSetvalidated

A struct to help with fmt::Debug implementations.

DebugStructvalidated

A struct to help with fmt::Debug implementations.

DebugTuplevalidated

A struct to help with fmt::Debug implementations.

Errorvalidated

The error type which is returned from formatting a message into a stream.

Formattervalidated

Configuration for formatting.

FromFnvalidated

Implements fmt::Debug and fmt::Display via the provided closure.

FormattingOptionsExperimentalvalidated

Options for formatting.

NumBufferExperimentalvalidated

A buffer wrapper of which the internal size is based on the maximum number of digits the associated integer can have.

Enums

Alignmentvalidated

Possible alignments returned by Formatter::align

DebugAsHexExperimentalvalidated

Specifies whether the Debug trait should use lower-/upper-case hexadecimal or normal integers.

SignExperimentalvalidated

The signedness of a Formatter (or of a FormattingOptions).

Traits

Binary

Display

Format trait for an empty format, {}.

LowerExp

e formatting.

LowerHex

x formatting.

Write

A trait for writing or formatting into Unicode-accepting buffers or streams.

NumBufferTraitExperimental

Trait used to describe the maximum number of digits in decimal base of the implemented integer.

Functions

from_fnvalidated

Creates a type whose fmt::Debug and fmt::Display impls are forwarded to the provided closure.

writevalidated

Takes an output stream and an Arguments struct that can be precompiled with the format_args! macro.

Type Aliases

Result

The type returned by formatter methods.

Derive Macros
