Enum GremlinParseError 

pub enum GremlinParseError {
    Runtime(AntlrError),
    Syntax {
        count: usize,
        tree: ParseTree,
    },
}

An error produced while parsing Gremlin text.

Variants

Runtime(AntlrError)

The lexer or parser failed outright (e.g. an unrecoverable error).

Syntax

The parser produced a tree but recovered from count syntax error(s); the input is not valid Gremlin. The recovered tree is provided for callers that want to inspect a best-effort result anyway.

Fields

count: usize

tree: ParseTree

Trait Implementations

impl Debug for GremlinParseError

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

impl Error for GremlinParseError

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<AntlrError> for GremlinParseError

fn from(e: AntlrError) -> Self

Converts to this type from the input type.
