Implementations

impl OciLoader

pub fn new(working_dir: impl Into<PathBuf>) -> Self

Creates a new OciLoader which builds temporary mount directory(s) in the given working_dir.

pub async fn load_app( &self, client: &mut Client, reference: &str, ) -> Result<ExecutableArtifact>

Pulls and loads an OCI Artifact and returns a LockedApp with the given OCI client and reference

pub async fn load_from_cache( &self, manifest: OciImageManifest, lockfile_path: PathBuf, reference: &str, cache: &Cache, ) -> Result<ExecutableArtifact, Error>

Loads an OCI Artifact from the given cache and returns a LockedApp with the given reference

pub async fn resolve_component_content_refs( &self, component: &mut LockedComponent, cache: &Cache, ) -> Result<()>

Resolves all digest references in the component (including source, dependencies, and asset files). Wasm sources are replaced with cache paths. Asset files are collected to a mount path, and the component files amended to reflect that.

This function assumes that:

1. All resolvable items have digest or inline sources.
2. All digest-addressed content is already in the cache.

If either of these is not true, the function errors.
