rama_http::layer::propagate_headers

Struct PropagateHeader

Source 
pub struct PropagateHeader<S> { /* private fields */ }
Expand description

Middleware that propagates headers from requests to responses.

If the header is present on the request it’ll be applied to the response as well. This could for example be used to propagate headers such as X-Request-Id.

See the module docs for more details.
