Errors during AST parsing.

Variants

TreeSitterFailed

tree-sitter failed to parse the source code.

LanguageSetFailed(String)

Failed to set language on parser.

InvalidSource

Invalid source code (not UTF-8).

InputTooLarge

Input exceeds maximum allowed size.

This error is returned by SafeParser when the input content exceeds the configured maximum size limit. This prevents unbounded memory allocation from pathological inputs.

Remediation

Split the file into smaller chunks or increase the --parser-max-bytes limit within the allowed bounds (1-32 MiB).

Fields

size: usize

Actual size of the input in bytes

max: usize

Maximum allowed size in bytes

file: Option<PathBuf>

Optional file path for debugging

ParseTimedOut

Parsing timed out.

This error is returned by SafeParser when tree-sitter parsing exceeds the configured timeout. This prevents runaway parsing on pathological inputs that could cause exponential backtracking.

Remediation

The file may contain malformed syntax causing parser pathology. Check the file for validity or increase the --parser-timeout-ms limit within bounds.

Fields

timeout_micros: u64

Timeout in microseconds

file: Option<PathBuf>

Optional file path for debugging

ParseCancelled

Parsing was cancelled by external request.

This error is returned when parsing is cancelled via a cancellation flag, typically used by the indexer to abort long-running parses proactively.

Fields

reason: String

Reason for cancellation

file: Option<PathBuf>

Optional file path for debugging

Other(String)

Other parse error.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<ParseError> for PluginError

fn from(source: ParseError) -> Self

Converts to this type from the input type.
