Struct SetResponseHeader

pub struct SetResponseHeader<S, M> { /* private fields */ }
Expand description

Middleware that sets a header on the response.

Implementations§

§

impl<S, M> SetResponseHeader<S, M>

pub fn overriding( inner: S, header_name: HeaderName, make: M, ) -> SetResponseHeader<S, M>

Create a new SetResponseHeader.

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

pub fn appending( inner: S, header_name: HeaderName, make: M, ) -> SetResponseHeader<S, M>

Create a new SetResponseHeader.

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( inner: S, header_name: HeaderName, make: M, ) -> SetResponseHeader<S, M>

Create a new SetResponseHeader.

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

pub fn get_ref(&self) -> &S

Gets a reference to the underlying service.

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.

§

impl<S, F, A> SetResponseHeader<S, BoxMakeHeaderValueFactoryFn<F, A>>

pub fn overriding_fn( inner: S, header_name: HeaderName, make_fn: F, ) -> SetResponseHeader<S, BoxMakeHeaderValueFactoryFn<F, A>>

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

See SetResponseHeader::overriding for more details.

pub fn appending_fn( inner: S, header_name: HeaderName, make_fn: F, ) -> SetResponseHeader<S, BoxMakeHeaderValueFactoryFn<F, A>>

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

See SetResponseHeader::appending for more details.

pub fn if_not_present_fn( inner: S, header_name: HeaderName, make_fn: F, ) -> SetResponseHeader<S, BoxMakeHeaderValueFactoryFn<F, A>>

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

See SetResponseHeader::if_not_present for more details.
