Everything that can go wrong talking to the native library.

Match on the variant for typed handling; Error::raw_status recovers the underlying transcribe_status code (0 for errors raised purely on the Rust side, e.g. the load-time version gate or a NUL in a caller string).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidArgument(String)

TRANSCRIBE_ERR_INVALID_ARG (or _SAMPLE_RATE).

NotImplemented(String)

TRANSCRIBE_ERR_NOT_IMPLEMENTED — the model has no path for this call.

ModelFileNotFound(String)

TRANSCRIBE_ERR_FILE_NOT_FOUND — the GGUF path does not exist.

ModelLoad(String)

TRANSCRIBE_ERR_GGUF / _UNSUPPORTED_ARCH / _UNSUPPORTED_VARIANT.

OutOfMemory(String)

TRANSCRIBE_ERR_OOM.

Backend(String)

TRANSCRIBE_ERR_BACKEND — the requested backend could not be satisfied.

Unsupported(String)

TRANSCRIBE_ERR_UNSUPPORTED_{TASK,LANGUAGE,TIMESTAMPS,PNC,ITN} — the model cannot satisfy this request shape.

BadStructSize(String)

TRANSCRIBE_ERR_BAD_STRUCT_SIZE — an ABI/struct-size fault. With the generated FFI this indicates a header/library skew, not caller error.

InputTooLong(String)

TRANSCRIBE_ERR_INPUT_TOO_LONG — audio longer than the model can decode.

Aborted

TRANSCRIBE_ERR_ABORTED — the abort callback returned true. The transcript of chunks that completed before the abort is preserved.

Fields

message: String

partial: Option<Box<Transcript>>

Partial transcript from chunks that completed before the abort.

OutputTruncated

TRANSCRIBE_ERR_OUTPUT_TRUNCATED — the decode hit the generation budget before end-of-stream; the transcript is incomplete by contract. The partial transcript is always preserved.

Fields

message: String

partial: Option<Box<Transcript>>

The (incomplete) transcript produced before truncation.

VersionMismatch(String)

The loaded library’s base version disagrees with the headers this crate was generated against (the pre-1.0 version lock). Raised on first use.

Nul(NulError)

A caller-supplied string contained an interior NUL byte.

Busy(String)

Another session of the same model already has a compute operation in flight. The C library serializes compute per model (the 0.x limitation): at most one run / batch / active stream across ALL of a model’s sessions at a time. Finish or drop the in-flight stream (one-shot runs/batches just queue) before starting another, or give each concurrent worker its own model. Raised purely on the Rust side, so Error::raw_status is 0.

Other(String)

A non-OK status with no more specific mapping.

Implementations

impl Error

pub fn raw_status(&self) -> i32

The transcribe_status this error was mapped from, or 0 for errors raised on the Rust side (version gate, NUL in a string, …).

pub fn partial(&self) -> Option<&Transcript>

The partial transcript carried by Error::Aborted / Error::OutputTruncated, if any. None for every other variant.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<NulError> for Error

fn from(source: NulError) -> Self

Converts to this type from the input type.
