source · [−]

pub struct Located<T, Loc: Display> {
    pub inner: T,
    pub location: Location<Loc>,
}

Expand description

Implementations

impl<T, Loc: Display> Located<T, Loc>

pub fn map_loc<F, Loc2>(self, tx: F) -> Located<T, Loc2> where
Loc2: Display,
F: FnMut(Loc) -> Loc2,

Maps an Located<T, Loc> to Located<T, Loc2> by applying a function to the contained location and moving the contained inner

Example

assert_eq!("blah".to_string()
                .to_located(BytePosition::from(5)..BytePosition::from(10))
                .map_loc(|BytePosition(o)| BytePosition(o+5)),
            Located{
                inner: "blah".to_string(),
                location: (BytePosition(ByteOffset(10))..BytePosition(ByteOffset(15))).into()
            });
