Function llg_validate_grammar

pub unsafe extern "C" fn llg_validate_grammar(
    init: &LlgConstraintInit,
    constraint_type: *const i8,
    data: *const i8,
    error_string: *mut i8,
    error_string_len: usize,
    warning_string: *mut i8,
    warning_string_len: usize,
) -> i32

Check if given grammar is valid. This about twice as fast as creating a matcher (which also validates). See llg_new_matcher() for the grammar format. Returns 0 on success and -1 on error and 1 on warning. The error message is written to error_string. The error_string is NUL-terminated. Same for warning_string.

Safety

This function should only be called from C code.
