pub fn space<'t, 's: 't, I>() -> impl Parser<'t, I, (), ParserError<'t, 's>> + Clonewhere
I: TokenInput<'t, 's>,Expand description
Match exactly one Token::Space.
Whitespace is a token rather than something skipped implicitly because
5 minutes is a time expression and 5minutes is not. A Space token
stands for a whole run of whitespace, so this also covers the repeated
one_of(" \t\n\r").at_least(1) the character-level grammar used.
