Enum ParseError 

pub enum ParseError {
    IoError {
        path: PathBuf,
        source: Error,
    },
    UnsupportedLanguage(PathBuf),
    ParserError(String),
    QueryError(String),
    EmptyFile(PathBuf),
}

Things that can go wrong when parsing source files.

Variants

IoError

Couldn’t read the file from disk.

Fields

path: PathBuf

source: Error

UnsupportedLanguage(PathBuf)

File extension doesn’t map to any supported language.

ParserError(String)

Tree-sitter failed to parse the source. Usually means the file has syntax errors or the parser hit an edge case.

QueryError(String)

Tree-sitter query compilation failed. Usually means the query pattern is invalid for the language grammar.

EmptyFile(PathBuf)

The file exists but is empty. Not really an error, but we surface it so callers can handle it gracefully.

Implementations

impl ParseError

pub fn io(path: impl Into<PathBuf>, source: Error) -> Self

Creates an IO error with the path for context.

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.
