Extension trait providing factory methods on ParseError.

Required Methods

fn new(msg: &str) -> ParseError

Create a generic parse error with a message.

fn at(msg: &str, line: u32, col: u32) -> ParseError

Create an error at a specific source location.

fn unexpected_token( found: &str, expected: &str, line: u32, col: u32, ) -> ParseError

Create an “unexpected token” error.

fn unexpected_eof() -> ParseError

Create an “unexpected end of file” error.

fn invalid_syntax(msg: &str, line: u32, col: u32) -> ParseError

Create an “invalid syntax” error.

fn unterminated_string(line: u32, col: u32) -> ParseError

Create an “unterminated string literal” error.

fn reserved_keyword(kw: &str, line: u32, col: u32) -> ParseError

Create a “reserved keyword used as identifier” error.

fn duplicate_binder(name: &str, line: u32, col: u32) -> ParseError

Create a “duplicate binder name” error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
