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. |
Parser | The parser structure for interpreting the input format string. This is
modelled as an iterator over |
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. |
Flag | Various flags which can be applied to format strings. The meaning of these flags is defined by the formatters themselves. |
Piece | A piece is a portion of the format string which represents the next part
