Available on crate feature alsa only.

Errors that can be raised by the ALSA layer.

Variants

Sys(Errno)

System error.

Io(Error)

I/O error.

FormatMismatch

Error raised when there’s a format mismatch between an underlying stream and the type attempting to be used with it.

Fields

ty: &'static str

A description of the type expected.

format: Format

The format that mismatched.

ChannelsMismatch

Error raised when there’s a channel count mismatch between an underlying stream and the type attempting to be used with it.

Fields

actual: usize

The actual number of channels.

expected: usize

The expected number of channels.

BadFormat(c_int)

Underlying function call returned an illegal format identifier.

BadAccess(c_uint)

Underlying function call returned an illegal access identifier.

BadTimestamp(c_uint)

Underlying function call returned an illegal timestamp identifier.

BadTimestampType(c_uint)

Underlying function call returned an illegal timestamp type identifier.

MissingPollFds

Underlying PCM was not set up for polling.

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<Errno> for Error

fn from(source: Errno) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
