pub struct FrameParser {
state: State,
cmd: u8,
len: u8,
payload: Vec<u8, MAX_PAYLOAD>,
}Expand description
Décodeur octet-par-octet : les octets USB arrivent en paquets de taille arbitraire, on accumule jusqu’à une trame complète. Resynchronise tout seul sur le start byte si on tombe au milieu d’un flux.

pub fn push(&mut self, byte: u8) -> Result<Option<Command>, ProtoError>
Pousse un octet. Renvoie :
Ok(Some(cmd))quand une trame complète et valide vient d’être décodée,Ok(None)quand il faut encore des octets,Err(_)sur trame invalide (le parser se réinitialise alors).
