ConversationEvent

Struct ConversationEvent 

Source
pub struct ConversationEvent { /* private fields */ }
Expand description

Opaque durable event emitted only by a protocol decision or canonical decode.

Neither header nor body fields are public, so a binding cannot manufacture a typed event from raw lifecycle values.

use liminal_protocol::lifecycle::ConversationEvent;

fn fabricate() {
    let _ = ConversationEvent {
        conversation_id: 7,
        ordinal: 0,
    };
}

Implementations§

Source§

impl ConversationEvent

Source

pub const fn conversation_id(&self) -> ConversationId

Returns the event’s owning conversation.

Source

pub const fn ordinal(&self) -> u64

Returns the event’s contiguous log ordinal.

Source

pub const fn encoded_len(&self) -> usize

Returns the exact canonical byte length of this event.

Source

pub fn encode_canonical(&self) -> Vec<u8>

Encodes the stable v1 event envelope in network byte order.

Source

pub fn decode_canonical( input: &[u8], ) -> Result<Self, ConversationEventDecodeError>

Decodes one exact canonical v1 event envelope.

§Errors

Returns ConversationEventDecodeError for truncation, an invalid magic prefix, an unsupported codec version or body tag, or any declared body length that differs from the complete supplied frame.
