Module chrono::format

Formatting (and parsing) utilities for date and time.

This module provides the common types and routines to implement, for example, DateTime::format or DateTime::parse_from_str methods. For most cases you should use these high-level interfaces.

Internally the formatting and parsing shares the same abstract formatting items, which are just an Iterator of the Item type. They are generated from more readable format strings; currently Chrono supports one built-in syntax closely resembling C’s strftime format.

Modules

strftime

strftime/strptime-inspired date and time formatting syntax.

Structs

DelayedFormat	A temporary object which can be used as an argument to format! or others. This is normally constructed via format methods of each date and time type.
InternalFixed	An opaque type representing fixed-format item types for internal uses only.
InternalNumeric	An opaque type representing numeric item types for internal uses only.
ParseError	An error from the parse function.
Parsed	Parsed parts of date and time. There are two classes of methods:

Enums

Fixed	Fixed-format item types.
Item	A single formatting item. This is used for both formatting and parsing.
Numeric	Numeric item types. They have associated formatting width (FW) and parsing width (PW).
Pad	Padding characters for numeric items.

Functions

format	Tries to format given arguments with given formatting items. Internally used by DelayedFormat.
format_item	Formats single formatting item
parse	Tries to parse given string into parsed with given formatting items. Returns Ok when the entire string has been parsed (otherwise parsed should not be used). There should be no trailing string after parsing; use a stray Item::Space to trim whitespaces.

Type Definitions

ParseResult

Same as Result<T, ParseError>.
