Expand description
A single formatting item. This is used for both formatting and parsing.
Variants
Literal(&'a str)
A literally printed and parsed text.
OwnedLiteral(Box<str, Global>)
Same as Literal
but with the string owned by the item.
Space(&'a str)
Whitespace. Prints literally but reads zero or more whitespace.
OwnedSpace(Box<str, Global>)
Same as Space
but with the string owned by the item.
Numeric(Numeric, Pad)
Numeric item. Can be optionally padded to the maximal length (if any) when formatting; the parser simply ignores any padded whitespace and zeroes.
Fixed(Fixed)
Fixed-format item.
Error
Issues a formatting error. Used to signal an invalid format string.
