Utilities for formatting and printing strings.

Structs§

Arguments: 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.
DebugList: A struct to help with fmt::Debug implementations.
DebugMap: A struct to help with fmt::Debug implementations.
DebugSet: A struct to help with fmt::Debug implementations.
DebugStruct: A struct to help with fmt::Debug implementations.
DebugTuple: A struct to help with fmt::Debug implementations.
Error: The error type which is returned from formatting a message into a stream.
Formatter: Configuration for formatting.
FormattingOptionsExperimental: Options for formatting.
FromFnExperimental: Implements fmt::Debug and fmt::Display using a function.
NumBufferExperimental: A buffer wrapper of which the internal size is based on the maximum number of digits the associated integer can have.

Alignment: Possible alignments returned by Formatter::align
DebugAsHexExperimental: Specifies whether the Debug trait should use lower-/upper-case hexadecimal or normal integers.
SignExperimental: The signedness of a Formatter (or of a FormattingOptions).

Binary: b formatting.
Debug: ? formatting.
Display: Format trait for an empty format, {}.
LowerExp: e formatting.
LowerHex: x formatting.
Octal: o formatting.
Pointer: p formatting.
UpperExp: E formatting.
UpperHex: 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.

write: Takes an output stream and an Arguments struct that can be precompiled with the format_args! macro.
from_fnExperimental: Creates a type whose fmt::Debug and fmt::Display impls are provided with the function f.
