Enum EncType 

pub enum EncType {
    PreKeyMessage,
    Message,
    SenderKey,
    MessageSecret,
}

Classification of an encryption node’s type.

Variants

PreKeyMessage

Pre-key Signal message ("pkmsg") — initial 1:1 session establishment.

Message

Regular Signal message ("msg") — established 1:1 session.

SenderKey

Sender-key message ("skmsg") — group encryption.

MessageSecret

Message-secret bot reply ("msmsg") — Meta AI / fbid bot envelope decrypted via crate::bot_message::decrypt_bot_message.

Implementations

impl EncType

pub fn from_wire(s: &str) -> Option<EncType>

Parse from the wire-format string in the type attribute.

pub fn as_wire_str(&self) -> &'static str

Returns the wire-format string.

pub fn is_session(&self) -> bool

Whether this is a 1:1 session-based encryption type (pkmsg or msg). msmsg is neither session- nor group-based; it has its own dispatch path.

pub fn is_bot_secret(&self) -> bool

True for the bot-secret envelope (msmsg). Mutually exclusive with session/group classification.
