Trait WithLocation 

pub trait WithLocation<L: Location>: Sized {
    // Provided methods
    fn at(self, span: impl Into<L>) -> Loc<Self, L>

Provided Methods

fn at(self, span: impl Into<L>) -> Loc<Self, L>

where Self: Sized,

Wrap Self in a location

fn at_loc<T: Sized>(self, loc: &Loc<T, L>) -> Loc<Self, L>

Creates a new Loc at the same source code location as another Loc

fn between(self, start: impl Into<L>, end: impl Into<L>) -> Loc<Self, L>

Create a location that spans start and end

fn between_locs<T, Y>(self, start: &Loc<T, L>, end: &Loc<Y, L>) -> Loc<Self, L>

Create a location that spans start and end

fn nowhere(self) -> Loc<Self, L>

where Self: Sized,

Create a Location which does not correspond to a source code location. Depending on how the lbirary is used in a compiler, this can either be a placeholder value, in which case encountering a nowhere when reporting an error is probably an error, or if source locations can be missing it should be an actual marker.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
