Struct SymbolIndex 

pub struct SymbolIndex { /* private fields */ }

Pre-computed symbol-to-file index for O(1) lookups.

Uses DashMap for lock-free concurrent reads and writes. Keys are Arc<str> for memory-efficient string interning — many lookups against the same symbol names benefit from shared allocations.

Implementations

impl SymbolIndex

pub fn new() -> Self

Create an empty symbol index.

pub fn build(&self, scope: &Path)

Build the index by walking all code files in scope.

Uses ignore::WalkBuilder with the same directory filtering as search (skipping .git, node_modules, target, etc.) and processes files in parallel via rayon for speed.

pub fn is_built(&self, scope: &Path) -> bool

Check if the index has been built for the given scope.

Simple heuristic: returns true if any indexed file path starts with scope.

pub fn lookup(&self, name: &str, scope: &Path) -> Vec<SymbolLocation>

Look up all locations of a symbol within scope.

Returns matching locations filtered to paths within scope. Results may include stale entries if files have changed since indexing – callers can check mtime against the current file if freshness matters.

pub fn lookup_definitions( &self, name: &str, scope: &Path, ) -> Vec<SymbolLocation>

Look up only definition locations of a symbol within scope.

Same as lookup but filters to is_definition == true.

pub fn index_file(&self, path: &Path, content: &str)

Index a single file, updating the symbol maps.

Used for incremental updates when a file changes. Removes old entries for this file before inserting new ones.

pub fn symbol_count(&self) -> usize

Number of unique symbol names in the index.

pub fn file_count(&self) -> usize

Number of indexed files.

Trait Implementations

impl Default for SymbolIndex

fn default() -> Self

Returns the “default value” for a type.
