rama::http::layer::set_header

Struct SetRequestHeaderLayer

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

Expand description

Layer that applies SetRequestHeader which adds a request header.

See SetRequestHeader for more details.

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.

§

impl SetRequestHeaderLayer<HeaderValue>

pub fn overriding_typed<H>(header: H) -> SetRequestHeaderLayer<HeaderValue>
where H: HeaderEncode,

Create a new SetRequestHeaderLayer from a typed HeaderEncode.

See SetRequestHeaderLayer::overriding for more details.

pub fn appending_typed<H>(header: H) -> SetRequestHeaderLayer<HeaderValue>
where H: HeaderEncode,

Create a new SetRequestHeaderLayer from a typed HeaderEncode.

See SetRequestHeaderLayer::appending for more details.

pub fn if_not_present_typed<H>(header: H) -> SetRequestHeaderLayer<HeaderValue>
where H: HeaderEncode,

Create a new SetRequestHeaderLayer from a typed HeaderEncode.

See SetRequestHeaderLayer::if_not_present for more details.

§

impl<F, A> SetRequestHeaderLayer<BoxMakeHeaderValueFn<F, A>>

pub fn overriding_fn( header_name: HeaderName, make_fn: F, ) -> SetRequestHeaderLayer<BoxMakeHeaderValueFn<F, A>>

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

See SetRequestHeaderLayer::overriding for more details.

pub fn appending_fn( header_name: HeaderName, make_fn: F, ) -> SetRequestHeaderLayer<BoxMakeHeaderValueFn<F, A>>

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

See SetRequestHeaderLayer::appending for more details.

pub fn if_not_present_fn( header_name: HeaderName, make_fn: F, ) -> SetRequestHeaderLayer<BoxMakeHeaderValueFn<F, A>>

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

See SetRequestHeaderLayer::if_not_present for more details.
