Trait ServiceExt

pub trait ServiceExt<R>: Service<R> + Sized {
    // Required method
    fn into_make_service(self) -> IntoMakeService<Self>;

    // Provided method
    fn handle_error<F, T>(self, f: F) -> HandleError<Self, F, T> { ... }
}

Extension trait that adds additional methods to any Service.

Required Methods

fn into_make_service(self) -> IntoMakeService<Self>

Convert this service into a MakeService, that is a Service whose response is another service.

This is commonly used when applying middleware around an entire Router. See “Rewriting request URI in middleware” for more details.

Provided Methods

fn handle_error<F, T>(self, f: F) -> HandleError<Self, F, T>

Convert this service into a HandleError, that will handle errors by converting them into responses.

See “error handling model” for more details.

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.
