Expand description

Callbacks invoked by the parser when it encounters invalid or unexpected input.

The parser does not abort on these conditions; it reports via your implementation and continues. Override the default no-op implementations to collect or log diagnostics. The crate module provides a diagnostics type that implements this trait and accumulates messages.

Provided Methods§

Source

fn emit_unknown_content(&mut self, text: &str, span: Span)

Called when the parser sees text it cannot interpret (e.g. invalid tokens).

Source

fn emit_unexpected(&mut self, actual: &str, expected: &[TokenType], span: Span)

Called when the parser expected one of expected token types but found actual.

Source

fn emit_parse_number_error( &mut self, value: &str, error: ParseNumberError, span: Span, )

Called when parsing a G/M/T number fails (e.g. overflow, invalid format).

Source

fn emit_parse_int_error( &mut self, value: &str, _error: ParseIntError, span: Span, )

Called when parsing an N or O number fails (e.g. invalid integer, overflow).
