Loudness measurement error.

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.

ChannelOutOfRange

A channel index is out of range for the configured layout.

Fields

index: usize

The requested channel index.

layout: usize

The channel count of the configured layout.

Finished

Push was called after finish().

ChannelMismatch

Too few samples provided for the channel count.

Fields

expected: usize

Number of channels expected.

got: usize

Number of channels provided.

InvalidSampleRate

A sample rate of zero was requested.

A loudness meter needs a positive sample rate to derive K‑weighting filter coefficients and to convert sample counts to seconds.

Fields

got: u32

The invalid sample rate requested.

NonFiniteSample

A non-finite sample (NaN or ±Infinity) was passed to the meter.

Non-finite values are rejected because they propagate through the IIR filter state and permanently poison all subsequent readings. The caller should either skip, replace, or clamp such samples before feeding them.

Fields

index: usize

The index of the non-finite sample in the push call.

channel: usize

The channel index (zero-based) of the non-finite sample.

value: f64

The non-finite value received.

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.
