Enum DecodeError 

#[non_exhaustive]
pub enum DecodeError {
    ExcessiveErrors {
        c0_errors: u32,
        total_errors: u32,
    },
}

Errors that can occur during AMBE frame decoding.

These errors represent conditions where the codec cannot produce reliable audio output. The decoder handles them internally by repeating the previous frame’s parameters (up to 3 times) and then muting to silence. Callers generally do not need to inspect these — AmbeDecoder::decode_frame always returns a valid PCM buffer, using silence as the fallback.

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.

ExcessiveErrors

Too many bit errors for the FEC to correct.

The Golay and Hamming decoders detected more errors than their correction capacity (3 bits for Golay, 1 bit for Hamming). The decoded parameters are unreliable and should not be used for synthesis.

Fields

c0_errors: u32

Errors detected in the C0 codeword (Golay-protected).

C0 carries the fundamental frequency index (b0), the most critical parameter. Even 1 error here can shift the pitch drastically.

total_errors: u32

Total errors across all four codewords (C0–C3).

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
