Assets

Struct Assets 

Source
pub struct Assets { /* private fields */ }
Expand description

A collection of EmbeddedFiles plus the Route table that maps served URLs to them.

You normally get one via the generated ASSETS static (see embed!), not by calling Assets::new yourself.

Implementations§

Source§

impl Assets

Source

pub const fn new( files: &'static [EmbeddedFile], routes: &'static [Route], ) -> Self

Construct an asset set from its files and route table. routes must be sorted by Route::url, and each Route::file must index into files; the build script guarantees both for the generated ASSETS static.

Source

pub fn resolve(&self, url: &str) -> Option<Resolved>

Resolve a served URL — a hashed_url like /assets/css/style.9f3a1c2b.css, or the plain url of an immutable_dir asset — to the file that answers it and the Cache-Control to send. This is the lookup ServeEmbedded uses; hand-rolled (non-tower) integrations call it to build a response themselves.

Source

pub fn get_logical(&self, logical: &str) -> Option<&'static EmbeddedFile>

Look up a file by its crate-root-relative logical_path, e.g. assets/css/style.css.

Source

pub fn url(&self, logical: &str) -> Option<&'static str>

The URL to reference an asset by, given its crate-root-relative path, e.g. url("assets/css/style.css")Some("/assets/css/style.9f3a1c2b.css"). Returns the cache-busted hashed_url when there is one, otherwise the plain url (for immutable_dir assets).

This is the runtime equivalent of the asset! macro, for cases where the asset name isn’t known at compile time. Prefer asset! when you can — it’s checked at compile time.

Source

pub fn iter(&self) -> impl Iterator<Item = &'static EmbeddedFile>

Iterate over every embedded file.

Source

pub fn len(&self) -> usize

How many files are embedded.

Source

pub fn is_empty(&self) -> bool

Whether there are no embedded files.

Source

pub fn service(&'static self) -> ServeEmbedded

A tower::Service that serves these assets.

Generated asset URLs are already full paths, so mount the service as a fallback (no nesting or prefix stripping):

Router::new().fallback_service(ASSETS.service())
