pub struct MetadataStore { /* private fields */ }

The SQLite metadata store.

Implementations

impl MetadataStore

pub fn open(path: &Path) -> Result<Self, MetaError>

Open or create a metadata database at the given path.

pub fn open_in_memory() -> Result<Self, MetaError>

Open an in-memory metadata database (for testing).

pub fn conn(&self) -> &Connection

Get a reference to the underlying SQLite connection.

Used internally for direct queries that don’t have dedicated methods.

pub fn store_patch(&self, patch: &Patch) -> Result<(), MetaError>

Store a patch in the metadata database.

pub fn get_patch(&self, id: &PatchId) -> Result<Patch, MetaError>

Retrieve a patch by ID.

pub fn set_branch( &self, name: &BranchName, target: &PatchId, ) -> Result<(), MetaError>

Store a branch pointer.

pub fn get_branch(&self, name: &BranchName) -> Result<PatchId, MetaError>

Get a branch target.

pub fn list_branches(&self) -> Result<Vec<(String, PatchId)>, MetaError>

List all branches.

pub fn store_edge( &self, parent: &PatchId, child: &PatchId, ) -> Result<(), MetaError>

Store a DAG edge.

pub fn get_edges( &self, patch_id: &PatchId, ) -> Result<(Vec<PatchId>, Vec<PatchId>), MetaError>

Get parent and child IDs for a patch.

pub fn working_set_add( &self, path: &RepoPath, status: FileStatus, ) -> Result<(), MetaError>

Add a file to the working set.

pub fn working_set_remove(&self, path: &RepoPath) -> Result<(), MetaError>

Remove a file from the working set.

pub fn working_set(&self) -> Result<Vec<(String, FileStatus)>, MetaError>

Get the working set.

pub fn set_config(&self, key: &str, value: &str) -> Result<(), MetaError>

Store a configuration value.

pub fn list_config(&self) -> Result<Vec<(String, String)>, MetaError>

List all config key-value pairs.

pub fn delete_config(&self, key: &str) -> Result<(), MetaError>

Delete a config key.

pub fn get_config(&self, key: &str) -> Result<Option<String>, MetaError>

Get a configuration value.

pub fn patch_count(&self) -> Result<i64, MetaError>

Get the number of patches stored.

pub fn store_public_key( &self, author: &str, public_key_bytes: &[u8], ) -> Result<(), MetaError>

pub fn get_public_key(&self, author: &str) -> Result<Option<Vec<u8>>, MetaError>

pub fn store_signature( &self, patch_id: &str, signature_bytes: &[u8], ) -> Result<(), MetaError>

pub fn get_signature( &self, patch_id: &str, ) -> Result<Option<Vec<u8>>, MetaError>

pub fn store_file_tree( &self, patch_id: &PatchId, tree: &FileTree, ) -> Result<(), MetaError>

Store a FileTree for a given patch ID.

Replaces all existing entries for that patch_id (DELETE + INSERT in transaction).

pub fn load_file_tree( &self, patch_id: &PatchId, ) -> Result<Option<FileTree>, MetaError>

Load a FileTree for a given patch ID from the database.

Returns None if no entries exist for that patch_id.

pub fn file_tree_contains( &self, patch_id: &PatchId, path: &str, ) -> Result<bool, MetaError>

Check if a path exists in the file tree for a given patch ID.

pub fn reflog_push( &self, old_head: &PatchId, new_head: &PatchId, message: &str, ) -> Result<(), MetaError>

Append an entry to the reflog.

pub fn reflog_list(&self) -> Result<Vec<(String, String, String)>, MetaError>

Get the full reflog (newest first).

pub fn reflog_clear(&self) -> Result<usize, MetaError>

Clear the entire reflog.
