Enum EbnfError 

pub enum EbnfError {
    Lexer(LexerError),
    Parser(ParserError),
    Normalization(String),
}

A failure while converting EBNF text to a grammar.

Variants

Lexer(LexerError)

The lexer rejected the input.

Parser(ParserError)

The parser rejected the token stream.

Normalization(String)

A normalization pass failed (mirrors C++ XGRAMMAR_LOG(FATAL) becoming a Python error).

Implementations

impl EbnfError

pub fn message(&self) -> &str

The human-readable message of the underlying error.

Trait Implementations

impl Clone for EbnfError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EbnfError

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

Formats the value using the given formatter.

impl Display for EbnfError

Formats the value using the given formatter.

impl Eq for EbnfError

impl Error for EbnfError

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.
