Enum ParseError 

pub enum ParseError {
    Lex(LexError),
    Language(LanguageError),
    Cancelled,
    InvalidEdit,
    InvalidSyntax(Span),
    Reconstruct(ReconstructError),
    UnsupportedNode {
        kind: String,
        span: Span,
    },
}

A failure while parsing or reconstructing a Tree-sitter syntax tree.

Variants

Lex(LexError)

The renaming hook could not inspect the source token stream.

Language(LanguageError)

The bundled grammar could not be installed in the parser.

Cancelled

Tree-sitter returned no tree.

InvalidEdit

A requested source edit did not lie on valid boundaries of the buffer.

InvalidSyntax(Span)

Tree-sitter produced an error or missing node at this span.

Reconstruct(ReconstructError)

The untyped Tree-sitter node could not reconstruct typed syntax.

UnsupportedNode

A valid concrete node has no representation in the typed schema.

Fields

kind: String

The Tree-sitter node kind that could not be lowered.

span: Span

The complete node range.

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<LexError> for ParseError

fn from(error: LexError) -> Self

Converts to this type from the input type.

impl From<ReconstructError> for ParseError

fn from(error: ReconstructError) -> Self

Converts to this type from the input type.
