Module fmt

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.

Enums

• 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).

Traits

• 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.

Functions

• 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.

Type Aliases

• Result
  The type returned by formatter methods.

Derive Macros

• Debug
  Derive macro generating an impl of the trait Debug.
