Struct EmbeddedAssets 

pub struct EmbeddedAssets { /* private fields */ }

Available on crate features axum and embed only.

Tower service that serves embedded assets via a byte-resolver closure.

Responses carry Cache-Control: public, max-age=31536000, immutable, which assumes Vite-style content-hashed filenames. Don’t route non-fingerprinted files (e.g. robots.txt, manifest.webmanifest) through this service — they would be cached for a year with no revalidation path.

Implementations

impl EmbeddedAssets

pub fn new<F>(resolver: F) -> Self

where F: Fn(&str) -> Option<Cow<'static, [u8]>> + Send + Sync + 'static,

Construct from a resolver. The closure receives the request path with the nest_service prefix already stripped and a leading / trimmed (e.g. assets/app-AAA.js) and returns the bytes, or None for 404.

pub fn mime( self, ext: impl Into<String>, content_type: impl Into<String>, ) -> Self

Add or override an extension → content-type mapping (extension without the dot, e.g. .mime("vtt", "text/vtt")).

Trait Implementations

impl Clone for EmbeddedAssets

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Service<Request<Body>> for EmbeddedAssets

type Response = Response<Body>

Responses given by the service.

type Error = !

Errors produced by the service.

type Future = Ready<Result<Response<Body>, !>>

The future response value.

fn poll_ready(&mut self, _cx: &mut Context<'_>) -> Poll<Result<(), Infallible>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, req: Request<Body>) -> Self::Future

Process the request and return the response asynchronously.
