pub fn take<Input>(n: usize) -> Take<Input> where
Input: RangeStream,
Expand description
Zero-copy parser which reads a range of length n
.
count_min_max
is a non-RangeStream
alternative.
let mut parser = take(1);
let result = parser.parse("1");
assert_eq!(result, Ok(("1", "")));
let mut parser = take(4);
let result = parser.parse("123abc");
assert_eq!(result, Ok(("123a", "bc")));
let result = parser.parse("abc");
assert!(result.is_err());
