Trait Location 

pub trait Location: Clone {
    // Required methods
    fn nowhere() -> Self;
    fn between(start: &Self, end: &Self) -> Self;
}

Trait to implement for types representing a source code location

Required Methods

fn nowhere() -> Self

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.

fn between(start: &Self, end: &Self) -> Self

Create a location that spans start to end. For example, this is used when creating a loc spanning a parenthesised expression from the start and end parens.

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.
