Struct luther::Location

pub struct Location(_);

An abstract location within a stream of tokens or characters.

Note that Location's are not orderable (that is, Location does not impl Ord or PartialOrd). The value of a Location cannot tell you whether it comes before or after some other Location in the same stream, just whether its equal or not equal to some other Location. It is possible to create a new Location from a usize or by adding a usize to an exising Location.

Panics

Adding a usize to a Location will panic if the resulting Location value is greater than usize::max_value().

Methods

impl Location

pub fn new(location: usize) -> Location

Create a new Location for a given starting point.
