Trait Locatable 

pub trait Locatable: Sized {
    type Located: Located;

    // Required method
    fn over(self, span: impl Into<Option<Span>>) -> Self::Located;
}

Add or set a Span to a type.

Locatable is for Located types that support changing their tracked Span, or for types that can be turned into Located types. The Locatable::over method is a builder method used to create a new object with a different Span, and the Located associated type tell the type of the result.

Example:

let term = term!(* x y).over(span);

Locatable can be automatically derived (see the corresponding proc-macro for details).

Required Associated Types

type Located: Located

Required Methods

fn over(self, span: impl Into<Option<Span>>) -> Self::Located

Turns self into an object of type Self::Located tracking the new span.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
