Implementations§

Source§

impl<M> SetResponseHeaderLayer<M>

Source

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

Create a new SetResponseHeaderLayer.

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

Source

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

Create a new SetResponseHeaderLayer.

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

Source

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

Create a new SetResponseHeaderLayer.

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