Struct SqliteGraphStore 

pub struct SqliteGraphStore { /* private fields */ }

A [GraphStore] backed by a SQLite database.

Implementations

impl SqliteGraphStore

pub fn open(path: impl AsRef<Path>) -> Result<Self>

Open (creating if absent, including parent directories) a file-backed store at path.

pub fn open_in_memory() -> Result<Self>

Open an ephemeral in-memory store.

pub fn remove_path(&mut self, path: &str)

Remove all rows for path (a file dropped from the view). Complements [GraphStore::insert], which replaces a path’s rows.

Trait Implementations

impl GraphStore for SqliteGraphStore

fn insert(&mut self, path: &str, graph: CodeGraph)

Insert (or replace) the slice assembled at path. Re-inserting the same path overwrites — slices are content-addressed and write-if-absent, never appended, so this cannot duplicate a file’s symbols.

fn symbols_in_file(&self, path: &str) -> Vec<Symbol>

Symbols defined in the slice at path.

fn definitions(&self, name: &str) -> Vec<Located<Symbol>>

Definitions matching name, each with the path it was found under (there may be several — names are unresolved).

fn references_to(&self, name: &str) -> Vec<Located<Reference>>

References whose target name is name, each with its path.

fn callers_of(&self, name: &str) -> Vec<String>

Distinct enclosing-function names that reference name.

fn callees(&self, name: &str) -> Vec<String>

Distinct names referenced from within name (the inverse of callers_of), sorted.

fn all_symbols(&self) -> Vec<Located<Symbol>>

Every symbol in the view, each with its path (used for whole-graph operations like diffing).

fn all_references(&self) -> Vec<Located<Reference>>

Every reference in the view, each with its path.

fn impact(&self, name: &str) -> Vec<String>

The transitive closure of callers: every symbol that could be affected if name changes, reached by walking callers_of breadth-first. Runs server-side (never ships the whole graph); the seed name is excluded, and cycles terminate via a visited set. Returned sorted.

fn overview(&self, largest: usize) -> ViewOverview

The aggregate shape of the whole view: counts, a breakdown by kind and by language, and the largest files by symbol count.

fn top(&self, ranking: Ranking, limit: usize) -> Page<RankedSymbol>

The top limit symbol names by ranking, descending.

fn list(&self, filter: &SymbolFilter, limit: usize) -> Page<Located<Symbol>>

Symbols matching filter, in path order, bounded by limit.

fn unreferenced( &self, filter: &SymbolFilter, exclude_tests: bool, limit: usize, ) -> Page<Located<Symbol>>

Symbols with no inbound reference anywhere in the view — dead-code candidates, in path then line order.
