Available on crate feature mtls only.
Expand description

Creates an iterator from input data and a parser.

Call the iterator’s ParserIterator::finish method to get the remaining input if successful, or the error value if we encountered an error.

On Err::Error, iteration will stop. To instead chain an error up, see cut.

use nom::{combinator::iterator, IResult, bytes::complete::tag, character::complete::alpha1, sequence::terminated};
use std::collections::HashMap;

let data = "abc|defg|hijkl|mnopqr|123";
let mut it = iterator(data, terminated(alpha1, tag("|")));

let parsed = it.map(|v| (v, v.len())).collect::<HashMap<_,_>>();
let res: IResult<_,_> = it.finish();

assert_eq!(parsed, [("abc", 3usize), ("defg", 4), ("hijkl", 5), ("mnopqr", 6)].iter().cloned().collect());
assert_eq!(res, Ok(("123", ())));
