Module fmt

Expand description

Text formatting utilities.

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.
DebugValue: A Value which serializes as a string using fmt::Debug.
Error: The error type which is returned from formatting a message into a stream.
FmtOption: A utility to assist with formatting Option values.
FormatWith: A wrapper type that formats the wrapped value using a provided function.
Formatter: Configuration for formatting.
WithIndent: Wraps a type implementing core::fmt::Write so that every newline written to that writer is indented a given amount.
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.
WriteExt: Extension trait adding additional methods to types implementing core::fmt::Write.
NumBufferTraitExperimental: Trait used to describe the maximum number of digits in decimal base of the implemented integer.

alt: Format the provided value using its core::fmt::Debug implementation, with “alternate mode” set
bin: Format the provided value using its core::fmt::Binary implementation.
comma_delimited: Formats a list of F-typed values to the provided writer, delimited with commas.
debug: Wraps a type implementing fmt::Debug as a Value that can be recorded using its Debug implementation.
display: Wraps a type implementing fmt::Display as a Value that can be recorded using its Display implementation.
hex: Format the provided value using its core::fmt::LowerHex implementation.
opt: Borrows an Option as a FmtOption that formats the inner value if the Option is Some, or emits a customizable string if the Option is None.
ptr: Format the provided value using its core::fmt::Pointer implementation.
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.
