/&str
).

T: ?Sized,
impl<T> PointerOffset<T> where
T: ?Sized,
pub fn new(offset: usize) -> Self
sourcepub fn translate_position(self, initial_slice: &T) -> usize
pub fn translate_position(self, initial_slice: &T) -> usize
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);
