Struct tower_http::set_header::SetResponseHeader

source · [−]

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

This is supported on crate feature set-header only.

Expand description

Middleware that sets a header on the response.

Implementations

source

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

source

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.

source

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.

source

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.

source

pub fn get_ref(&self) -> &S

Gets a reference to the underlying service.

source

pub fn get_mut(&mut self) -> &mut S

Gets a mutable reference to the underlying service.

source

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.
