Struct libpulse_binding::error::PAErr

#[repr(transparent)]
pub struct PAErr(pub i32);

A wrapper around integer errors returned by PulseAudio. Can be converted to a Code variant for comparison purposes if desired.

Tuple Fields

0: i32

Implementations

impl PAErr

pub fn to_string(&self) -> Option<String>

Converts an integer error value, as returned by many PA C API functions, to a human readable string.

Trait Implementations

impl Clone for PAErr

fn clone(&self) -> PAErr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PAErr

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

Formats the value using the given formatter.

impl Display for PAErr

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

Formats the value using the given formatter.

impl Error for PAErr

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Code> for PAErr

fn from(c: Code) -> Self

Converts to this type from the input type.

impl PartialEq<PAErr> for PAErr

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<PAErr> for Code

fn try_from(e: PAErr) -> Result<Self, Self::Error>

Attempts to convert the wrapped integer error value to a Code variant.

Returns Err(()) if the value cannot be mapped.

type Error = ()

The type returned in the event of a conversion error.
