Implementations

impl<M> SetRequestHeaderLayer<M>

pub fn overriding(header_name: HeaderName, make: M) -> SetRequestHeaderLayer<M>

Create a new SetRequestHeaderLayer.

If a previous value exists for the same header, it is removed and replaced with the new header value.

pub fn appending(header_name: HeaderName, make: M) -> SetRequestHeaderLayer<M>

Create a new SetRequestHeaderLayer.

The new header is always added, preserving any existing values. If previous values exist, the header will have multiple values.

pub fn if_not_present( header_name: HeaderName, make: M, ) -> SetRequestHeaderLayer<M>

Create a new SetRequestHeaderLayer.

If a previous value exists for the header, the new value is not inserted.
