Struct combine::stream::PointerOffset

[+] Show declaration

pub struct PointerOffset(pub usize);

[−] Expand description

Newtype around a pointer offset into a slice stream (&[T]/&str).

Implementations

impl PointerOffset[−]

pub fn translate_position<T>(self, initial_string: &T) -> usize where
    T: ?Sized, [−]

Converts the pointer-based position into an indexed position.

let text = "b";
let err = token('a').easy_parse(text).unwrap_err();
assert_eq!(err.position.0, text.as_ptr() as usize);
assert_eq!(err.map_position(|p| p.translate_position(text)).position, 0);
