CheckerState Type checker state using NodeArena and Solver type system. Interner String interner that deduplicates strings and returns Atom handles. Parser High-performance parser using Node architecture (16 bytes/node).
This is the optimized path for Phase 8 test suite evaluation. ScannerState The scanner state that holds the current position and token information. ShardedInterner Sharded string interner for concurrent use. WasmProgram Multi-file TypeScript program for cross-file type checking. WasmTransformContext Opaque wrapper for transform directives across the wasm boundary. Comparison Comparison result for ordering operations.
Matches TypeScript’s Comparison const enum in src/compiler/corePublic.ts ModuleKind Module system kind. NewLineKind New line kind for source file emission. ScriptTarget ECMAScript target version. SyntaxKind Syntax kind enum matching TypeScript’s SyntaxKind.
This enum contains only the token types produced by the scanner (0-186).
AST node types are not included here. TokenFlags Token flags indicating special properties of scanned tokens. ALT_DIRECTORY_SEPARATOR Alternative directory separator (backslash, used on Windows). DIRECTORY_SEPARATOR Directory separator used internally (forward slash). MAX_CALL_DEPTH Maximum depth for function call resolution. MAX_INSTANTIATION_DEPTH Maximum depth for generic type instantiation. compare_strings_case_insensitive Compare two strings using a case-insensitive ordinal comparison. compare_strings_case_insensitive_eslint_compatible Compare two strings using a case-insensitive ordinal comparison (eslint-compatible). compare_strings_case_sensitive Compare two strings using a case-sensitive ordinal comparison. create_parser Create a new Parser for the given source text.
This is the recommended parser for production use. create_program Create a new multi-file program. create_scanner Create a new scanner for the given source text.
This is the wasm-bindgen entry point for creating scanners from JavaScript. ensure_trailing_directory_separator Ensures a path has a trailing directory separator. equate_strings_case_insensitive Check if two strings are equal (case-insensitive).
Uses iterator-based comparison to avoid allocating new strings. equate_strings_case_sensitive Check if two strings are equal (case-sensitive). file_extension_is Check if path ends with a specific extension. get_base_file_name Returns the path except for its containing directory name (basename).
Uses char-based operations for UTF-8 safety. has_extension Determines whether a path has an extension. has_trailing_directory_separator Determines whether a path has a trailing separator (/ or \\). is_any_directory_separator Determines whether a charCode corresponds to / or \. is_ascii_letter Check if character is an ASCII letter (A-Z, a-z). is_digit Check if character is a decimal digit (0-9). is_hex_digit Check if character is a hexadecimal digit (0-9, A-F, a-f). is_line_break Check if character is a line break (LF, CR, LS, PS). is_octal_digit Check if character is an octal digit (0-7). is_white_space_like Check if character is any whitespace (including line breaks). is_white_space_single_line Check if character is a single-line whitespace (not including line breaks). is_word_character Check if character is a word character (A-Z, a-z, 0-9, _). keyword_to_text Get the text representation of a keyword token.
WASM-exported version that allocates a String for JS compatibility. keyword_to_text_static Internal non-allocating version - returns static str reference.
Use this for Rust-internal code to avoid allocations. normalize_slashes Normalize path separators, converting \ into /. path_is_relative Determines whether a path starts with a relative path component (i.e. . or ..). punctuation_to_text Get the text representation of a punctuation token.
WASM-exported version that allocates a String for JS compatibility. punctuation_to_text_static Internal non-allocating version - returns static str reference.
Use this for Rust-internal code to avoid allocations. remove_trailing_directory_separator Removes a trailing directory separator from a path, if it has one.
Uses char-based operations for UTF-8 safety. string_to_token Get the token kind for a given text, including identifiers and keywords.
Returns Identifier if the text is not a keyword. text_to_keyword Convert a string to its keyword SyntaxKind, if it’s a keyword.
Returns None if the text is not a keyword. to_file_name_lower_case Convert file name to lowercase for case-insensitive file systems. token_is_assignment_operator token_is_identifier_or_keyword token_is_keyword token_is_literal token_is_punctuation token_is_reserved_word token_is_strict_mode_reserved_word token_is_template_literal token_is_trivia
