Struct BundleSource 

pub struct BundleSource { /* private fields */ }

The built-in source: bytes served out of registered .lpak bundles.

A bundle is reachable two ways. A lumen://app/<key> URI addresses it directly, and once Self::set_root names the directory the archive was packed from, an ordinary path under that directory resolves to the matching key as well, so markup that names icons/sun.png works whether the app ships loose files or an archive. Bundled entries win over files on disk, which is what lets an app ship the archive alone.

Implementations

impl BundleSource

pub fn register(&mut self, bundle: LumenBundle)

Adds a bundle. Bundles are consulted in registration order and the first hit wins.

pub fn set_root(&mut self, root: impl Into<PathBuf>)

Declares the directory the registered bundles were packed from.

pub fn bundles(&self) -> &[LumenBundle]

The registered bundles, in registration order.

pub fn read_uri(&self, uri: &str) -> Option<Vec<u8>>

Resolves a lumen://app/<key> URI. None when no bundle holds the key or the URI uses another scheme.

Trait Implementations

impl AssetSource for BundleSource

fn read(&self, path: &Path) -> Option<Vec<u8>>

Returns the bytes for path, or None to let the next source (and ultimately the filesystem) answer.

impl Clone for BundleSource

fn clone(&self) -> BundleSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for BundleSource

fn default() -> BundleSource

Returns the “default value” for a type.
