Module core::fmt

Utilities for formatting and printing strings.

Modules

• builders 🔒
• float 🔒
• macros 🔒
• num 🔒
  Integer and floating-point number formatting
• rt 🔒 Experimental
  These are the lang items used by format_args!().

Macros

• fmt_refs 🔒
• last_type 🔒
• maybe_tuple_doc 🔒
• peel 🔒
• tuple 🔒

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.
• PostPadding 🔒
  Padding after the end of something. Returned by Formatter::padding.

Enums

• Alignment
  Possible alignments returned by Formatter::align

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

• getcount 🔒 ^⚠
• pointer_fmt_inner 🔒
  Since the formatting will be identical for all pointer types, use a non-monomorphized implementation for the actual formatting to reduce the amount of codegen work needed.
• run 🔒 ^⚠
• write
  The write function takes an output stream, and an Arguments struct that can be precompiled with the format_args! macro.

Type Definitions

• Result
  The type returned by formatter methods.

Derive Macros

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