DirectoryPackageStore

eqiora::package

Struct DirectoryPackageStore 

pub struct DirectoryPackageStore { /* private fields */ }
Description

A caller-rooted local store backed by an open directory capability.

The root and entries are opened without following a symlink in their final path component. After construction, entries are opened relative to the retained root handle, so renaming or replacing the caller’s root path cannot redirect a load. Only <root>/<expected-digest>.json can be read.

A load returns bytes read from one opened entry; it is not a filesystem snapshot and does not prevent concurrent in-place mutation. The resolver independently decodes and revalidates every returned release identity.

Implementations§

§

impl DirectoryPackageStore

Signature links:§DirectoryPackageStore

pub fn try_from_dir(root: Dir) -> Result<DirectoryPackageStore, StoreError>

Signature links:try_from_dirResultDirectoryPackageStoreStoreError

Retain a caller-opened directory capability without acquiring ambient filesystem authority.

§Errors

Returns a typed root error when the supplied handle cannot be inspected as a directory.

pub fn open_ambient( root: impl Into<PathBuf>, ) -> Result<DirectoryPackageStore, StoreError>

Signature links:open_ambientIntoPathBufResultDirectoryPackageStoreStoreError

Open and retain one explicit store root with ambient authority.

The caller-selected path is the only ambient lookup. Its final component is opened without following a symbolic link. Every later load remains relative to the retained directory handle.

§Errors

Returns a path-aware root error when the explicit root cannot be opened as a non-symlink directory.
