}

Unified error type for all codemod-core operations.

Variants

PatternInference(String)

Pattern inference failed — the engine could not derive a transformation pattern from the provided before/after examples.

Parse(String)

AST parsing failed — tree-sitter could not produce a valid syntax tree for the given source code.

Scan(String)

Scanning error — something went wrong while walking the filesystem or matching patterns across files.

Transform(String)

Transformation error — the engine failed to apply a pattern transformation to a source file.

Rule(String)

Rule error — a codemod rule file could not be loaded, parsed, or failed validation.

Matching(String)

Pattern matching error.

Io(Error)

File I/O error — a filesystem operation (read, write, create directory, etc.) failed.

Yaml(Error)

YAML serialization/deserialization error.

Json(Error)

JSON serialization/deserialization error.

UnsupportedLanguage(String)

Language not supported.

Validation(String)

Validation failed.

Other(String)

Catch-all for other errors.

Trait Implementations

impl Debug for CodemodError

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

Formats the value using the given formatter.

impl Display for CodemodError

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

Formats the value using the given formatter.

impl Error for CodemodError

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.
