Trait ContextWithLocation 

pub trait ContextWithLocation<'a> {
    type Location: Location<'a>;

    // Required method
    fn context_location(&self) -> &Self::Location;
}

A context type for quoted snippets (q!(...)) from which a crate::location::Location can be extracted.

This is implemented both for bare locations (used when splicing quoted values, such as the argument to crate::location::Location::source_iter) and for OperatorContext (used when splicing quoted closures passed to operators on live collections). Free variables that only depend on the location of the splice site (such as crate::location::cluster::CLUSTER_SELF_ID) are generic over this trait so that they can be captured in both kinds of quoted snippets.

Required Associated Types

type Location: Location<'a>

The location type of this context.

Required Methods

fn context_location(&self) -> &Self::Location

Extracts the location of the splice site from this context.

Dyn Compatibility

This trait is dyn compatible.

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