#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_string_to_int(
    stack: Stack,
) -> Stack

Convert String to Int: ( String – Int Int ) Returns the parsed int and 1 on success, or 0 and 0 on failure. Accepts integers in range [-9223372036854775808, 9223372036854775807] (i64). Trims leading/trailing whitespace before parsing. Leading zeros are accepted (e.g., “007” parses to 7).

Safety

Stack must have a String value on top
