Struct tower_http::set_header::SetRequestHeader[−][src]

pub struct SetRequestHeader<S, M> { /* fields omitted */ }
This is supported on crate feature set-header only.
Expand description

Middleware that sets a header on the request.

Implementations

impl<S, M> SetRequestHeader<S, M>[src]

pub fn overriding(inner: S, header_name: HeaderName, make: M) -> Self[src]

Create a new SetRequestHeader. 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[src]

Create a new SetRequestHeader. 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[src]

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

pub fn get_ref(&self) -> &S[src]

Gets a reference to the underlying service.

pub fn get_mut(&mut self) -> &mut S[src]

Gets a mutable reference to the underlying service.

pub fn into_inner(self) -> S[src]

Consumes self, returning the underlying service.
