Struct HtmlRewriteLayer 

pub struct HtmlRewriteLayer<H> { /* private fields */ }

Available on crate feature html only.

Layer that applies HtmlRewrite to the responses of the wrapped service.

See the module docs.

Implementations

impl<H> HtmlRewriteLayer<H>

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

Creates a new HtmlRewriteLayer that rewrites elements matching selectors with handler (the handler is cloned per response, so it starts fresh for each one).

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 rewrite_body<B>(&self, body: B) -> HtmlRewriteBody<B, H>

where H: ElementContentHandler + Clone,

Wraps a body directly using this layer’s selector set and handler.

This is useful for services that need request-specific gating before deciding whether a single response body should be rewritten, while still sharing the same layer configuration.

Trait Implementations

impl<H: Clone> Clone for HtmlRewriteLayer<H>

fn clone(&self) -> HtmlRewriteLayer<H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S, H: Clone> Layer<S> for HtmlRewriteLayer<H>

type Service = HtmlRewrite<S, H>

The service produced by the layer.

fn layer(&self, inner: S) -> Self::Service

Wrap the given service with the middleware, returning a new service.

fn into_layer(self, inner: S) -> Self::Service
