Struct ra_ap_base_db::FileSet

pub struct FileSet { /* private fields */ }

A set of VfsPaths identified by FileIds.

Implementations

impl FileSet

pub fn len(&self) -> usize

Returns the number of stored paths.

pub fn resolve_path(&self, path: AnchoredPath<'_>) -> Option<FileId>

Get the id of the file corresponding to path.

If either path’s anchor or the resolved path is not in the set, returns None.

pub fn file_for_path(&self, path: &VfsPath) -> Option<&FileId>

Get the id corresponding to path if it exists in the set.

pub fn path_for_file(&self, file: &FileId) -> Option<&VfsPath>

Get the path corresponding to file if it exists in the set.

pub fn insert(&mut self, file_id: FileId, path: VfsPath)

Insert the file_id, path pair into the set.

Note

Multiple FileId can be mapped to the same VfsPath, and vice-versa.

pub fn iter(&self) -> impl Iterator<Item = FileId>

Iterate over this set’s ids.

Trait Implementations

impl Clone for FileSet

fn clone(&self) -> FileSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for FileSet

fn default() -> FileSet

Returns the “default value” for a type.

impl PartialEq<FileSet> for FileSet

fn eq(&self, other: &FileSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
