Struct FetchedPkg 

pub struct FetchedPkg {
    pub cache_path: PathBuf,
    pub sha: String,
    pub manifest: Option<Manifest>,
    pub resolved_tag: Option<String>,
}

Result of a successful Fetcher::fetch call.

Fields

cache_path: PathBuf

Absolute path to the cloned repository on disk.

sha: String

The resolved commit SHA (40-character hex string).

manifest: Option<Manifest>

The parsed mlua-pkg.toml found at cache_path, if present.

resolved_tag: Option<String>

The concrete tag name actually resolved. Equals dep.tag for exact pins; for prefix pins (e.g. "v0.1") holds the picked release (e.g. "v0.1.0"). None when no tag pin was used (rev / branch / HEAD resolution).

Implementations

impl FetchedPkg

pub fn at_root( cache_path: PathBuf, sha: String, resolved_tag: Option<String>, ) -> Result<FetchedPkg, PkgError>

Describe a package whose root directory is already on disk (a cache checkout or a patch_dir): read the author manifest and assemble the FetchedPkg. Shared by the cache-hit, clone and patch paths.

Without an mlua-pkg.toml, an in-tree LuaRocks rockspec (root or rockspecs/, see rockspec::find_in_tree) is evaluated and turned into a synthesized author manifest whose entry is folded from build.modules. A rockspec that cannot be evaluated is an error; one that yields no entry hint (C modules, irregular layout) leaves manifest as None.

Errors

PkgError::ManifestParse / PkgError::Validation from the manifest or rockspec, PkgError::Io from directory listing.
