Struct ModuleResolver 

pub struct ModuleResolver { /* private fields */ }

Module resolver that implements TypeScript’s resolution algorithms

Implementations

impl ModuleResolver

pub fn new(options: &ResolvedCompilerOptions) -> Self

Create a new module resolver with the given options

pub fn node_resolver() -> Self

Create a resolver with default Node resolution

pub fn resolve( &mut self, specifier: &str, containing_file: &Path, specifier_span: Span, ) -> Result<ResolvedModule, ResolutionFailure>

Resolve a module specifier from a containing file

pub fn resolve_with_kind( &mut self, specifier: &str, containing_file: &Path, specifier_span: Span, import_kind: ImportKind, ) -> Result<ResolvedModule, ResolutionFailure>

Resolve a module specifier from a containing file, with import kind information. The import_kind is used to determine whether to emit TS2834 (extensionless ESM import) or TS2307 (cannot find module) for extensionless imports in Node16/NodeNext.

pub fn probe_js_file( &mut self, specifier: &str, containing_file: &Path, specifier_span: Span, import_kind: ImportKind, ) -> Option<PathBuf>

Probe for a JS file that would resolve for this specifier.

Used for TS7016: when normal resolution fails but a JS file exists, we can report “Could not find declaration file” instead of “Cannot find module”. Returns the resolved JS file path if found.

pub fn clear_cache(&mut self)

Clear the resolution cache

pub const fn resolution_kind(&self) -> ModuleResolutionKind

Get the current resolution kind

pub fn emit_resolution_error( &self, diagnostics: &mut DiagnosticBag, failure: &ResolutionFailure, )

Emit TS2307 error for a resolution failure into a diagnostic bag

All module resolution failures emit TS2307 “Cannot find module” error. This includes:

• NotFound: Module specifier could not be resolved
• InvalidSpecifier: Module specifier is malformed
• PackageJsonError: Package.json is missing or invalid
• CircularResolution: Circular dependency detected during resolution
• PathMappingFailed: Path mapping from tsconfig did not resolve

Trait Implementations

impl Debug for ModuleResolver

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

Formats the value using the given formatter.
