Struct DependencyIndex 

pub struct DependencyIndex { /* private fields */ }

Global cross-project dependency index backed by SQLite.

Thread safety

The underlying rusqlite::Connection is guarded by a Mutex so DependencyIndex is Send + Sync.

Implementations

impl DependencyIndex

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

Open or create the dependency index at the given path.

Creates parent directories if they do not exist, opens the database in WAL mode, and initialises the schema.

Errors

Returns DependencyIndexError::Io if the parent directory cannot be created, or DependencyIndexError::Sqlite if the database cannot be opened or the schema cannot be initialised.

pub fn index_project( &self, project_root: &Path, ) -> Result<usize, DependencyIndexError>

Parse a project manifest file and index its dependencies.

Detects the manifest type from files present in project_root and inserts all discovered dependencies. Returns the count of rows inserted.

Errors

Returns DependencyIndexError::Io if the manifest cannot be read, or DependencyIndexError::Parse if the manifest is malformed, or DependencyIndexError::Sqlite if a database write fails.

pub fn projects_using( &self, dependency: &str, ) -> Result<Vec<DependencyEntry>, DependencyIndexError>

Query: which projects depend on the given library?

Errors

Returns DependencyIndexError::Sqlite if the query fails.

pub fn dependencies_of( &self, project_path: &str, ) -> Result<Vec<DependencyEntry>, DependencyIndexError>

Query: what does the given project depend on?

Errors

Returns DependencyIndexError::Sqlite if the query fails.
