Enum TtsError 

pub enum TtsError {
    Connect(String),
    VoiceFetch(String),
    Parse(String),
    Ws(Box<Error>),
    Io(Error),
    NoAudio,
}

All ways a synthesis request can fail.

Callers typically propagate this with ? or match on a variant to decide whether to retry (e.g. TtsError::Connect after a network blip).

Variants

Connect(String)

The WebSocket handshake or DRM-token auth failed after all retry attempts. The inner string is the last underlying error message.

VoiceFetch(String)

The voice-catalogue HTTPS fetch failed (DNS, transport, HTTP framing). The inner string is the underlying error message.

Parse(String)

A voice-list JSON body could not be deserialized. The inner string is the underlying serde error message.

Ws(Box<Error>)

Transport-level WebSocket error (handshake, frame decode, TLS).

The tungstenite::Error is boxed to keep TtsError small: it is the largest variant and threads through every Result<_, TtsError> on the stack. Boxing it allocates only on the rare error path.

Io(Error)

I/O error on the underlying TCP stream, including receive idle timeout.

NoAudio

The turn completed (or the stream closed) without any audio frames.

Trait Implementations

impl Debug for TtsError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for TtsError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for TtsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for TtsError

fn from(source: Error) -> TtsError

Converts to this type from the input type.

impl From<Error> for TtsError

fn from(e: Error) -> TtsError

Converts to this type from the input type.
