Struct tower::util::BoxService

pub struct BoxService<T, U, E> { /* fields omitted */ }

A boxed Service + Send trait object.

BoxService turns a service into a trait object, allowing the response future type to be dynamic. This type requires both the service and the response future to be Send.

See module level documentation for more details.
