Struct JsonRewrite 

pub struct JsonRewrite<S, H> { /* private fields */ }

Rewrites JSON response bodies of the underlying service, using rama’s streaming JsonRewriter.

See the module docs for details. Construct it directly with new or via JsonRewriteLayer.

Implementations

impl<S, H> JsonRewrite<S, H>

pub fn new( inner: S, selectors: impl IntoIterator<Item = JsonPath>, handler: H, ) -> Self

Creates a new JsonRewrite service.

The selector index passed to the handler is the index into selectors; keep the two aligned.

pub fn with_rewrite_policy( self, policy: impl Fn(&HeaderMap, &Extensions) -> bool + Send + Sync + 'static, ) -> Self

Sets a custom response rewrite policy.

The predicate receives the response headers and extensions and can narrow rewriting beyond the built-in Content-Encoding guard.

pub fn set_rewrite_policy( &mut self, policy: impl Fn(&HeaderMap, &Extensions) -> bool + Send + Sync + 'static, ) -> &mut Self

Sets a custom response rewrite policy.

The predicate receives the response headers and extensions and can narrow rewriting beyond the built-in Content-Encoding guard.

pub fn with_max_buffered_bytes(self, max_buffered_bytes: usize) -> Self

Sets the tokenizer buffered-input limit for each rewritten body.

pub fn set_max_buffered_bytes(&mut self, max_buffered_bytes: usize) -> &mut Self

Sets the tokenizer buffered-input limit for each rewritten body.

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.

Trait Implementations

impl<S: Clone, H: Clone> Clone for JsonRewrite<S, H>

fn clone(&self) -> JsonRewrite<S, H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug, H> Debug for JsonRewrite<S, H>

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

Formats the value using the given formatter.

impl<S, H, ReqBody, ResBody> Service<Request<ReqBody>> for JsonRewrite<S, H>

where S: Service<Request<ReqBody>, Output = Response<ResBody>>, ResBody: StreamingBody<Data: Send + 'static, Error: Into<BoxError> + Send + 'static> + Send + 'static, H: JsonValueHandler + Clone + Send + Sync + 'static, ReqBody: Send + 'static,

type Output = Response<JsonRewriteBody<ResBody, H>>

The type of the output returned by the service.

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

The type of error returned by the service.

async fn serve( &self, req: Request<ReqBody>, ) -> Result<Self::Output, Self::Error>

Serve an output or an error for the given input

fn boxed(self) -> BoxService<Input, Self::Output, Self::Error>

Box this service to allow for dynamic dispatch.
