Function parse_result_free

func parse_result_free(self: ParseResult*)

Free a public parse result and all owned AST arenas.

Parameters:

• self: Parse result to free.

Function parse_has_errors

func parse_has_errors(self: ParseResult*) -> bool

Report whether parsing produced any errors.

Parameters:

• self: Parse result to inspect.

Returns: true if the parse diagnostics contain an error.

Function parse_diag_count

func parse_diag_count(self: ParseResult*) -> int

Return the number of diagnostics produced during parsing.

Parameters:

• self: Parse result to inspect.

Returns: Total diagnostic count.

Function parse_diag_get

func parse_diag_get(self: ParseResult*, index: int) -> Diagnostic*

Return a parse diagnostic by index.

Parameters:

• self: Parse result to inspect.
• index: Zero-based diagnostic index.

Returns: Diagnostic at index.

Function impl_result_to_public

func impl_result_to_public(self: ImplParseResult*) -> ParseResult*

Convert the internal parser result to the public parse-result type.

Parameters:

• self: Internal parse result to consume.

Returns: Public parse result owning the same AST arenas and diagnostics.

Function parse_module_tokens

func parse_module_tokens(tokens: TokenVector, filename: string) -> ParseResult*

Parse a module from an existing token stream.

Parameters:

• tokens: Token stream to parse.
• filename: Source filename used in diagnostics.

Returns: Parse result for the module.

Function parse_module_tokens_owned

func parse_module_tokens_owned(tokens: TokenVector, filename: string) -> ParseResult*

Parse a module from an existing token stream and free the token buffer.

Parameters:

• tokens: Token stream to parse.
• filename: Source filename used in diagnostics.

Returns: Parse result for the module.

Function parse_lex_error_result

func parse_lex_error_result(ls: LexerState*, filename: string) -> ParseResult*

Convert lexer diagnostics into a public parse result and free the lexer state.

Parameters:

• ls: Lexer state holding diagnostics.
• filename: Source filename used in diagnostics.

Returns: Parse result containing the copied lexer diagnostics.

Function parse_module_source

func parse_module_source(source: string, filename: string) -> ParseResult*

Lex and parse a module from source text.

Parameters:

• source: Source text to parse.
• filename: Source filename used in diagnostics.

Returns: Parse result for the module.
