Module fmt

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.

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.

Functions

• 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.
