Struct combine::primitives::PointerOffset
[−]
[src]
pub struct PointerOffset(pub usize);
Newtype around a pointer offset into a slice stream (&[T]
/&str
).
Methods
impl PointerOffset
[src]
fn translate_position<T: ?Sized>(self, initial_string: &T) -> usize where
T: ,
T: ,
Converts the pointer-based position into an indexed position.
let text = "b"; let err = token('a').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);
