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 backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Code> for PAErr

fn from(c: Code) -> Self

Performs the conversion.

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: &PAErr) -> bool

This method tests for !=.

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.
