Module core::fmt [] [src]

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, so no constructors are given and the fields are private to prevent modification.

Error

The error type which is returned from formatting a message into a stream.

Formatter

A struct to represent both where to emit formatting strings to and how they should be formatted. A mutable version of this is passed to all formatting traits.

DebugList [Unstable]

A struct to help with fmt::Debug implementations.

DebugMap [Unstable]

A struct to help with fmt::Debug implementations.

DebugSet [Unstable]

A struct to help with fmt::Debug implementations.

DebugStruct [Unstable]

A struct to help with fmt::Debug implementations.

DebugTuple [Unstable]

A struct to help with fmt::Debug implementations.

Radix [Unstable]

A radix with in the range of 2..36.

RadixFmt [Unstable]

A helper type for formatting radixes.

Traits

Binary

Format trait for the b character

Debug

Format trait for the :? format. Useful for debugging, all types should implement this.

Display

When a value can be semantically expressed as a String, this trait may be used. It corresponds to the default format, {}.

LowerExp

Format trait for the e character

LowerHex

Format trait for the x character

Octal

Format trait for the o character

Pointer

Format trait for the p character

UpperExp

Format trait for the E character

UpperHex

Format trait for the X character

Write

A collection of methods that are required to format a message into a stream.

Functions

write

The write function takes an output stream, a precompiled format string, and a list of arguments. The arguments will be formatted according to the specified format string into the output stream provided.

radix [Unstable]

Constructs a radix formatter in the range of 2..36.

Type Definitions

Result

The type returned by formatter methods.
