Unstable (rustc_private)

Macro support for format strings

These structures are used when parsing format strings for the compiler. Parsing does not happen at runtime: structures of std::fmt::rt are generated instead.

Structs

Argument	[Unstable] Representation of an argument specification.
FormatSpec	[Unstable] Specification for the formatting of an argument in the format string.
Parser	[Unstable] The parser structure for interpreting the input format string. This is modeled as an iterator over Piece structures to form a stream of tokens being output.

Enums

Alignment	[Unstable] Enum of alignments which are supported.
Count	[Unstable] A count is used for the precision and width parameters of an integer, and can reference either an argument or a literal integer.
Flag	[Unstable] Various flags which can be applied to format strings. The meaning of these flags is defined by the formatters themselves.
Piece	[Unstable] A piece is a portion of the format string which represents the next part to emit. These are emitted as a stream by the Parser class.
Position	[Unstable] Enum describing where an argument for a format can be located.
