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>)`

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>)`

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.
