Trait Implementations

impl Clone for AlsaError

fn clone(&self) -> AlsaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlsaError

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

Formats the value using the given formatter.

impl Display for AlsaError

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

Formats the value using the given formatter.

impl From<AlsaError> for AudioError

fn from(err: AlsaError) -> Self

Converts to this type from the input type.

impl PartialEq for AlsaError

fn eq(&self, other: &AlsaError) -> 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.
