Trait chumsky::text::TextParser [−][src]
pub trait TextParser<I: Character, O>: Parser<I, O> {
fn padded(self) -> Padded<Self, I, O>
where
Self: Sized,
{ ... }
}Expand description
A trait containing text-specific functionality that extends the Parser trait.
Provided methods
Parse a pattern, ignoring any amount of whitespace both before and after the pattern.
The output type of this parser is O, the same as the original parser.
Examples
let ident = text::ident::<_, Simple<char>>().padded();
// A pattern with no whitespace surrounding it is accepted
assert_eq!(ident.parse("hello"), Ok("hello".to_string()));
// A pattern with arbitrary whitespace surrounding it is also accepted
assert_eq!(ident.parse(" \t \n \t world \t "), Ok("world".to_string()));
