pub struct PointerOffset(pub usize);
Newtype around a pointer offset into a slice stream (&[T]
/&str
).

[src]
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);
