Enum DecodeError 

pub(crate) enum DecodeError {
    EmptyInput,
    UnsupportedBitrate(u32),
    EncoderInit(BuildError),
    Encode(EncodeError),
}

Errors that can occur during the AMBE-to-MP3 decode pipeline.

Wraps the two external library error types (mp3lame_encoder::BuildError and mp3lame_encoder::EncodeError) into a single enum so that callers only need to handle one error type from decode_to_mp3.

Variants

EmptyInput

No AMBE frames were provided — nothing to decode.

UnsupportedBitrate(u32)

The requested bitrate does not correspond to a valid LAME CBR bitrate. Valid values: 8, 16, 24, 32, 40, 48, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps).

EncoderInit(BuildError)

Failed to initialize the LAME MP3 encoder (memory allocation failure or invalid parameter combination).

Encode(EncodeError)

Failed during MP3 encoding of the PCM buffer.

Trait Implementations

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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<BuildError> for DecodeError

fn from(e: BuildError) -> Self

Converts to this type from the input type.

impl From<EncodeError> for DecodeError

fn from(e: EncodeError) -> Self

Converts to this type from the input type.
