Struct MapResponseBodyLayer

Source

pub struct MapResponseBodyLayer<F> { /* private fields */ }

Expand description

Apply a transformation to the response body.

See the module docs for an example.

Implementations§

Source §

impl<F> MapResponseBodyLayer<F>

Source

pub const fn new(f: F) -> Self

Create a new MapResponseBodyLayer.

F is expected to be a function that takes a body and returns another body.

Source §

impl<Body> MapResponseBodyLayer<fn(Body) -> Body>
where Body: StreamingBody<Data = Bytes, Error: Into<BoxError>> + Send + Sync + 'static,

Source

pub const fn new_boxed_streaming_body() -> Self

Turn the StreamingBody into a crate::Body using crate::Body::new.

This is shorthand for MapResponseBodyLayer::new(Body::new).

Source §

impl<Body> MapResponseBodyLayer<fn(Body) -> Body>
where Body: From<Body>,

Source

pub const fn into_boxed_streaming_body() -> Self

Turn the body into a crate::Body using crate::Body::from.

This is shorthand for MapResponseBodyLayer::new(Body::from).
