Replaced with nom8::character::digit1 with input wrapped in nom8::input::Streaming
Expand description
Recognizes one or more ASCII numerical characters: 0-9
Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there’s not enough input data,
or if no terminating token is found (a non digit character).
Example
assert_eq!(digit1::<_, (_, ErrorKind)>("21c"), Ok(("c", "21")));
assert_eq!(digit1::<_, (_, ErrorKind)>("c1"), Err(Err::Error(("c1", ErrorKind::Digit))));
assert_eq!(digit1::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));WARNING: Deprecated, replaced with nom8::character::digit1 with input wrapped in nom8::input::Streaming
