Configurable endpoint resolver implementation.

Required Methods

fn resolve_endpoint<'a>( &'a self, params: &'a EndpointResolverParams, ) -> EndpointFuture<'a>

Asynchronously resolves an endpoint to use from the given endpoint parameters.

Provided Methods

fn finalize_params<'a>( &'a self, _params: &'a mut EndpointResolverParams, ) -> Result<(), BoxError>

Finalize the service-specific concrete parameters in _params.

The EndpointResolverParams may need to include additional data at a later point, after its creation in the read_before_execution method of an endpoint parameters interceptor. Modifying it directly within the ResolveEndpoint::resolve_endpoint method is not feasible, as params is passed by reference. This means that incorporating extra data would require cloning params within the method. However, the return type EndpointFuture has a lifetime tied to the input argument, making it impossible to return the cloned params, as its lifetime is scoped to the method.

Dyn Compatibility

This trait is dyn compatible.

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