Struct Located

Source 
pub struct Located<I, E> { /* private fields */ }
Expand description

An internal type used to facilitate error prioritisation. You shouldn’t need to interact with this type during normal use of the crate.

Implementations§

Source§

impl<I, E: Error<I>> Located<I, E>

Source

pub fn at(at: usize, error: E) -> Self

Create a new Located with the give input position and error.

Source

pub fn max(self, other: impl Into<Option<Self>>) -> Self

Get the maximum of two located errors. If they hold the same position in the input, merge them.

Source

pub fn map<U, F: FnOnce(E) -> U>(self, f: F) -> Located<I, U>

Map the error with the given function.
