Function add_error_at_eof

pub fn add_error_at_eof<S: Into<String>>(
    parser: &Parser,
    driver: &mut Driver,
    error: S,
)

Emits an error diagnostic at the end of the source file.

The diagnostic will be ignored if the parser is being used in a call to Parser::disable_diagnostics_during. This is a helper function which simplifies the construction of error diagnostics when the parser is at EOF.
