Enum FrameKind 

pub enum FrameKind {
    Abridged,
    Intermediate,
    Full {
        send_seqno: Arc<AtomicU32>,
        recv_seqno: Arc<AtomicU32>,
    },
    Obfuscated {

    },
    FakeTls {
        cipher: Arc<Mutex<ObfuscatedCipher>>,

    },
}

How framing bytes are sent/received on a connection.

Obfuscated carries an Arc<Mutex<ObfuscatedCipher>> so the same cipher state is shared (safely) between the writer task (TX / encrypt) and the reader task (RX / decrypt). The two directions are separate AES-CTR instances inside ObfuscatedCipher, so locking is only needed to prevent concurrent mutation of the struct, not to serialise TX vs RX.

Variants

Abridged

Intermediate

Full

Fields

send_seqno: Arc<AtomicU32>

recv_seqno: Arc<AtomicU32>

Obfuscated

Obfuscated2 over Abridged framing.

Fields

cipher: Arc<Mutex<ObfuscatedCipher>>

PaddedIntermediate

Obfuscated2 over Intermediate+padding framing (0xDD MTProxy).

Fields

cipher: Arc<Mutex<ObfuscatedCipher>>

FakeTls

FakeTLS framing (0xEE MTProxy). Same Obfuscated2/PaddedIntermediate transport as PaddedIntermediate, carried inside a decoy TLS handshake + TLS record byte-stream framing. cipher is the real data cipher (a fresh Obfuscated2 keypair generated after the decoy handshake completes) – never derived from the ClientHello HMAC.

Fields

cipher: Arc<Mutex<ObfuscatedCipher>>

tls_raw_pending: Arc<Mutex<Vec<u8>>>

Raw wire bytes not yet unwrapped from TLS record framing (may hold a partial trailing record between reads).

decoded_pending: Arc<Mutex<Vec<u8>>>

Decrypted PaddedIntermediate-stream bytes extracted from complete TLS records but not yet consumed by frame peeling.

Trait Implementations

impl Clone for FrameKind

fn clone(&self) -> FrameKind
