Struct SourceManager 

pub struct SourceManager { /* private fields */ }

A manager for sources.

This version replaces DashMap with a single inner structure protected by a high-performance RwLock (from the parking_lot crate) and uses AHashMap for speed.

Implementations

impl SourceManager

pub fn new(interner: ThreadedInterner) -> Self

Creates a new source manager.

pub fn insert_path( &self, name: impl AsRef<str>, path: PathBuf, category: SourceCategory, ) -> SourceIdentifier

Inserts a source with the given name and file path.

pub fn insert_content( &self, name: impl AsRef<str>, content: impl AsRef<str>, category: SourceCategory, ) -> SourceIdentifier

Inserts a source with the given name and content.

pub fn contains(&self, source_id: &SourceIdentifier) -> bool

Returns whether the manager contains a source with the given identifier.

pub fn source_ids(&self) -> Vec<SourceIdentifier>

Returns all source identifiers.

pub fn source_ids_for_category( &self, category: SourceCategory, ) -> Vec<SourceIdentifier>

Returns source identifiers for the given category.

pub fn source_ids_except_category( &self, category: SourceCategory, ) -> Vec<SourceIdentifier>

Returns source identifiers for categories other than the given one.

pub fn load(&self, source_id: &SourceIdentifier) -> Result<Source, SourceError>

Loads the source for the given identifier.

If the source content is already loaded, it is returned immediately. Otherwise the file is read from disk, processed, and cached.

pub fn write( &self, source_id: SourceIdentifier, new_content: impl AsRef<str>, ) -> Result<(), SourceError>

Writes updated content for the source with the given identifier.

pub fn len(&self) -> usize

Returns the number of sources.

pub fn is_empty(&self) -> bool

Returns true if there are no sources.
