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
  Representation of an argument specification.
• FormatSpec
  Specification for the formatting of an argument in the format string.
• InnerSpan
  Range inside of a Span used for diagnostics when we only have access to relative positions.
• InnerWidthMapping
  The location and before/after width of a character whose width has changed from its source code representation
• ParseError
• Parser
  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
  Enum of alignments which are supported.
• Count
  A count is used for the precision and width parameters of an integer, and can reference either an argument or a literal integer.
• DebugHex
  Enum for the debug hex flags.
• ParseMode
  The type of format string that we are parsing.
• Piece
  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
  Enum describing where an argument for a format can be located.
• Sign
  Enum for the sign flags.
