Enum Payload 

pub enum Payload {
    Config(WebSocketConfig),
    Start(SynthesisRequest),
    Text(String),
    End(WebSocketEnd),
    Cancel(WebSocketCancel),
}

Variants

Config(WebSocketConfig)

Connection-level configuration. At most one, and only before the first start. Not required in debug mode or when the upgrade request carried an Authorization header.

Start(SynthesisRequest)

Opens the context with the full synthesis parameters. A non-empty text is the complete input for one-shot synthesis: audio streams and ends with done, no end required. An empty text opens a streaming context that stays open for text messages and finalizes on end.

Text(String)

Appends a chunk of input text to an open streaming context (one opened with an empty start.text). The engine meters, segments, and synthesizes it into the same continuous audio as it arrives. Rejected with kind “invalid_input” if the context is not open for input (no start, or already ended / one-shot).

End(WebSocketEnd)

Declares end of input for a streaming context. Remaining audio is delivered, followed by done. A no-op for a one-shot context. The connection stays open for further contexts.

Cancel(WebSocketCancel)

Aborts the context immediately, discarding in-flight synthesis. Acknowledged with cancelled; idempotent (cancelling an unknown or finished context is not an error).

Implementations

impl Payload

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Payload>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.
