Struct FileResolver 

pub struct FileResolver<'a> { /* private fields */ }

Performs file resolution by applying import paths and mappings.

Implementations

impl<'a> FileResolver<'a>

pub fn new(source_map: &'a SourceMap) -> Self

Creates a new file resolver.

pub fn configure_from_sess(&mut self, sess: &Session)

Configures the file resolver from a session.

pub fn clear(&mut self)

Clears the internal state.

pub fn set_current_dir(&mut self, current_dir: &Path)

Sets the current directory.

Panics

Panics if current_dir is not an absolute path.

pub fn add_include_paths(&mut self, paths: impl IntoIterator<Item = PathBuf>)

Adds include paths.

pub fn add_include_path(&mut self, path: PathBuf)

Adds an include path.

pub fn add_import_remappings( &mut self, remappings: impl IntoIterator<Item = ImportRemapping>, )

Adds import remappings.

pub fn add_import_remapping(&mut self, remapping: ImportRemapping)

Adds an import remapping.

pub fn source_map(&self) -> &'a SourceMap

Returns the source map.

pub fn current_dir(&self) -> &Path

Returns the current directory, or . if it could not be resolved.

pub fn try_current_dir(&self) -> Option<&Path>

Returns the current directory, if resolved successfully.

pub fn canonicalize(&self, path: &Path) -> Result<PathBuf>

Canonicalizes a path using Self::current_dir.

pub fn normalize<'b>(&self, path: &'b Path) -> Cow<'b, Path>

Normalizes a path removing unnecessary components.

Does not perform I/O.

pub fn make_absolute<'b>(&self, path: &'b Path) -> Cow<'b, Path>

Makes the path absolute by joining it with the current directory.

Does not perform I/O.

pub fn resolve_file( &self, path: &Path, parent: Option<&Path>, ) -> Result<Arc<SourceFile>, ResolveError>

Resolves an import path.

parent is the path of the file that contains the import, if any.

pub fn remap_path<'b>( &self, path: &'b Path, parent: Option<&Path>, ) -> Cow<'b, Path>

Applies the import path mappings to path.

pub fn load_stdin(&self) -> Result<Arc<SourceFile>, ResolveError>

Loads stdin into the source map.

pub fn try_file( &self, path: &Path, ) -> Result<Option<Arc<SourceFile>>, ResolveError>

Loads path into the source map. Returns None if the file doesn’t exist.

Trait Implementations

impl<'a> Debug for FileResolver<'a>

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
