Error code.

These represent the i32 error codes returned by many of the underlying PulseAudio C functions. Beware, these enum values are positive values, whilst PA functions return them in negative form, i.e. the Invalid variant here has a value of 3, while functions returning this error code return -3. (This is identical to the enum provided in the PA C API).

Variants

Ok = 0

No error.

Access = 1

Access failure.

Command = 2

Unknown command.

Invalid = 3

Invalid argument.

Exist = 4

Entity exists.

NoEntity = 5

No such entity.

ConnectionRefused = 6

Connection refused.

Protocol = 7

Protocol error.

Timeout = 8

AuthKey = 9

No authentication key.

Internal = 10

ConnectionTerminated = 11

Killed = 12

Entity killed.

InvalidServer = 13

ModInitFailed = 14

BadState = 15

NoData = 16

Version = 17

Incompatible protocol version.

TooLarge = 18

Data too large.

NotSupported = 19

Operation not supported.

Unknown = 20

The error code was unknown to the client.

NoExtension = 21

Extension does not exist.

Obsolete = 22

Obsolete functionality.

NotImplemented = 23

Missing implementation.

Forked = 24

The caller forked without calling execve() and tried to reuse the context.

IO = 25

An IO error happened.

Busy = 26

Device or resource busy.

impl PartialEq for pa_error_code_t

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

impl ToPrimitive for pa_error_code_t

fn to_i64(&self) -> Option<i64>

Converts the value of self to an i64. If the value cannot be represented by an i64, then None is returned.
