Struct Sources 

pub struct Sources { /* private fields */ }

Register of loaded source files and their syntax trees.

Source file definitions (SourceFile) are stored in a vector (Vec<Rc<SourceFile>>) and mapped by hash, path and name via index to this vector.

The root model (given at creation) will be stored but will only be accessible by hash and path but not by it’s qualified name.

Implementations

impl Sources

pub fn load(root: Rc<SourceFile>, search_paths: &[PathBuf]) -> ParseResult<Self>

Create source cache

Inserts the root file and loads all files from search_paths.

pub fn root(&self) -> Rc<SourceFile>

Return root file.

pub fn resolve(&self) -> ResolveResult<SymbolMap>

Create initial symbol map from externals.

pub fn name_by_path(&self, filename: &Path) -> ResolveResult<QualifiedName>

Return the qualified name of a file by it’s path

pub fn get_by_src_ref( &self, referrer: &impl SrcReferrer, ) -> ResolveResult<Rc<SourceFile>>

Convenience function to get a source file by from a SrcReferrer.

pub fn ref_str(&self, referrer: &impl SrcReferrer) -> String

Return a string describing the given source code position.

pub fn get_by_path(&self, path: &Path) -> ResolveResult<Rc<SourceFile>>

Find a project file by it’s file path.

pub fn get_name_by_hash(&self, hash: u64) -> ResolveResult<&QualifiedName>

Get qualified name of a file by hash value.

pub fn get_by_name(&self, name: &QualifiedName) -> ResolveResult<Rc<SourceFile>>

Find a project file by the qualified name which represents the file path.

pub fn search_paths(&self) -> &Vec<PathBuf>

Return search paths of this cache.
