Struct tower_http::propagate_header::PropagateHeader

source · [−]

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

This is supported on crate feature propagate-header only.

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.
