Enum Error 

#[non_exhaustive]
pub enum Error {
    UnsupportedBitrate(u16),
    UnsupportedSampleRate(u32),
    FrameBodyLengthMismatch {
        expected: usize,
        actual: usize,
    },
    BadSyncOrReservedField,
    UnsupportedLayer,
}

Errors from MPEG audio (Layer III) mux/demux.

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.

UnsupportedBitrate(u16)

bitrate_kbps is not one of the 14 standard Layer III rates for this MpegVersion.

UnsupportedSampleRate(u32)

sample_rate is not one of the 3 standard rates for this MpegVersion.

FrameBodyLengthMismatch

frame_body.len() doesn’t match FrameHeader::frame_len() - 4 (header size).

Fields

expected: usize

Expected body length (frame_len() - 4).

actual: usize

Actual frame_body.len() passed in.

BadSyncOrReservedField

The next 3 bytes are not a valid frame sync + version/layer/bitrate/samplerate combination.

UnsupportedLayer

Layer is not Layer III (01) — only Layer III is supported by this crate.

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.
