I m wondering the problem came from here

https://github.com/tazz4843/whisper-rs/blob/4dca14d5ec88fb7e420d46789656628b8e191bec/src/whisper_grammar.rs#L9

we should align msvc special type just to be u32

#[cfg_attr(any(not(windows), target_env = "gnu"), repr(u32))] // include windows-gnu
#[cfg_attr(all(windows, not(target_env = "gnu")), repr(u32))] // msvc being *special* again
#[derive(Debug, Copy, Clone, PartialEq, Eq, Hash)]
pub enum WhisperGrammarElementType {
    /// End of rule definition
    End = whisper_gretype_WHISPER_GRETYPE_END,
    /// Start of alternate definition for a rule
    Alternate = whisper_gretype_WHISPER_GRETYPE_ALT,
    /// Non-terminal element: reference to another rule
    RuleReference = whisper_gretype_WHISPER_GRETYPE_RULE_REF,
    /// Terminal element: character (code point)
    Character = whisper_gretype_WHISPER_GRETYPE_CHAR,
    /// Inverse of a character(s)
    NotCharacter = whisper_gretype_WHISPER_GRETYPE_CHAR_NOT,
    /// Modifies a preceding [Self::Character] to be an inclusive range
    CharacterRangeUpper = whisper_gretype_WHISPER_GRETYPE_CHAR_RNG_UPPER,
    /// Modifies a preceding [Self::Character] to add an alternate character to match
    CharacterAlternate = whisper_gretype_WHISPER_GRETYPE_CHAR_ALT,
}
