Struct FileProvider 

pub struct FileProvider { /* private fields */ }

Provider for finding files in the project.

Uses git ls-files via [ProcessSpawner] as the fast path (respects .gitignore, works on remote hosts), then falls back to recursive directory walking via the [FileSystem] trait.

File enumeration runs on a background thread to avoid blocking the UI. When the cache is empty, suggestions() returns a “Loading…” placeholder and kicks off a background task. When the task finishes it sends an AsyncMessage::QuickOpenFilesLoaded which the editor handles by calling set_cache() and refreshing the prompt.

Implementations

impl FileProvider

pub fn new( filesystem: Arc<dyn FileSystem + Send + Sync>, process_spawner: Arc<dyn ProcessSpawner>, runtime_handle: Option<Handle>, async_sender: Option<Sender<AsyncMessage>>, ) -> Self

pub fn set_backends( &mut self, filesystem: Arc<dyn FileSystem + Send + Sync>, process_spawner: Arc<dyn ProcessSpawner>, )

Re-point this provider at a new authority’s filesystem + process spawner (e.g. after setAuthority / a remote attach swaps the backend).

The spawner is the important one: quick-open’s fast path is git ls-files through process_spawner, so a stale local spawner would list host files in a remote session. The cached file list is from the old backend, so it’s cleared (which also cancels any in-flight walk).

pub fn clear_cache(&self)

Clear the file cache (e.g., after file system changes).

pub fn cancel_loading(&self)

Cancel any in-progress background file load. Called when the user closes Quick Open so we don’t keep walking.

pub fn set_cache(&self, cwd: &str, files: Arc<Vec<FileEntry>>)

Update the file cache with final results from a completed background load. Dropped if cwd no longer matches the cache’s in-flight cwd — i.e. the user switched projects mid-load, so these results are stale.

pub fn set_partial_cache(&self, cwd: &str, files: Arc<Vec<FileEntry>>)

Update the file cache with partial results while the background scan is still running. Unlike [set_cache], this keeps loading = true.

pub fn record_access(&self, path: &str)

Record file access for frecency ranking

Trait Implementations

impl Clone for FileProvider

fn clone(&self) -> FileProvider

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl QuickOpenProvider for FileProvider

fn prefix(&self) -> &str

The prefix that triggers this provider (e.g., “>”, “#”, “:”) Empty string means this is the default provider (no prefix)

fn suggestions( &self, query: &str, context: &QuickOpenContext, ) -> Vec<Suggestion>

Generate suggestions for the given query

fn on_select( &self, suggestion: Option<&Suggestion>, query: &str, _context: &QuickOpenContext, ) -> QuickOpenResult

Handle selection of a suggestion

fn as_any(&self) -> &dyn Any

Downcast support for concrete provider access (e.g., updating cache).

fn as_any_mut(&mut self) -> &mut dyn Any

Mutable downcast support, for re-pointing concrete provider state (e.g. swapping the FileProvider’s filesystem + process spawner when the active authority changes).
