Struct PropagateHeaderLayer

Source

pub struct PropagateHeaderLayer { /* private fields */ }

Available on crate feature propagate-header only.

Expand description

Layer that applies PropagateHeader which 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.
