Enum TSParseError 

pub enum TSParseError {
    Language(LanguageError),
    TreeUnavailable,
}

Errors that can occur during tree-sitter parsing operations.

Tree-sitter parsing can fail for several reasons, from language compatibility issues to timeout problems. These errors provide information about what went wrong during the parsing process.

Variants

Language(LanguageError)

The language grammar is incompatible with the parser.

Occurs when trying to assign a language that the parser can’t handle, typically due to version mismatches between the tree-sitter library and the language grammar.

TreeUnavailable

Tree-sitter failed to parse the input within the configured constraints.

Can be caused by several conditions:

• Parsing timeout exceeded (see Parser::set_timeout_micros)
• Cancellation flag was triggered (see Parser::set_cancellation_flag)
• No language was assigned to the parser (see Parser::set_language)
• The input was too complex or malformed for the parser to handle

Tree-sitter doesn’t provide detailed error information, so this covers all general parsing failures.

Trait Implementations

impl Debug for TSParseError

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

Formats the value using the given formatter.

impl Display for TSParseError

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

Formats the value using the given formatter.

impl Error for TSParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<LanguageError> for TSParseError

fn from(source: LanguageError) -> Self

Converts to this type from the input type.
