pub struct SetResponseHeaderLayer<M> { /* private fields */ }

Layer that applies SetResponseHeader which adds a response header.

See SetResponseHeader for more details.

Implementations

impl SetResponseHeaderLayer<HeaderValue>

pub fn overriding_typed<H: Header>(header: H) -> Self

Create a new SetResponseHeaderLayer from a typed Header.

See SetResponseHeaderLayer::overriding for more details.

pub fn appending_typed<H: Header>(header: H) -> Self

Create a new SetResponseHeaderLayer from a typed Header.

See SetResponseHeaderLayer::appending for more details.

pub fn if_not_present_typed<H: Header>(header: H) -> Self

Create a new SetResponseHeaderLayer from a typed Header.

See SetResponseHeaderLayer::if_not_present for more details.

impl<M> SetResponseHeaderLayer<M>

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.

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.

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.

impl<F, A> SetResponseHeaderLayer<BoxMakeHeaderValueFactoryFn<F, A>>

pub fn overriding_fn(header_name: HeaderName, make_fn: F) -> Self

Create a new SetResponseHeaderLayer from a [super::MakeHeaderValueFn].

See SetResponseHeaderLayer::overriding for more details.

pub fn appending_fn(header_name: HeaderName, make_fn: F) -> Self

Create a new SetResponseHeaderLayer from a [super::MakeHeaderValueFn].

See SetResponseHeaderLayer::appending for more details.

pub fn if_not_present_fn(header_name: HeaderName, make_fn: F) -> Self

Create a new SetResponseHeaderLayer from a [super::MakeHeaderValueFn].

See SetResponseHeaderLayer::if_not_present for more details.
