Struct tower_async_http::set_header::SetResponseHeader

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

Available on crate feature set-header only.

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) -> Self

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) -> Self

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) -> Self

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 get_mut(&mut self) -> &mut S

Gets a mutable reference to the underlying service.

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.

Trait Implementations

impl<S: Clone, M: Clone> Clone for SetResponseHeader<S, M>

fn clone(&self) -> SetResponseHeader<S, M>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, M> Debug for SetResponseHeader<S, M>where S: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<ReqBody, ResBody, S, M> Service<Request<ReqBody>> for SetResponseHeader<S, M>where S: Service<Request<ReqBody>, Response = Response<ResBody>>, M: MakeHeaderValue<Response<ResBody>> + Clone,

type Response = <S as Service<Request<ReqBody>>>::Response

Responses given by the service.

type Error = <S as Service<Request<ReqBody>>>::Error

Errors produced by the service.

async fn call( &mut self, req: Request<ReqBody> ) -> Result<Self::Response, Self::Error>

Process the request and return the response asynchronously.
