Struct QueueInfo 

pub struct QueueInfo { /* private fields */ }

A GObject-derived object to express information of queue.

A QueueInfo is a GObject-derived object to express information of queue. The call of queue_info_by_id() and queue_info_by_name() returns the instance of object. The call of UserClientExtManual::create_queue() and UserClientExt::update_queue() requires the instance of object.

The object wraps struct snd_seq_queue_info in UAPI of Linux sound subsystem.

Properties

client-id

The numeric ID of client which owns the queue, including one of ALSASeqSpecificClientId.

Readable | Writeable

locked

Whether to be locked by the other queues or not.

Readable | Writeable

name

The name of queue.

Readable | Writeable

queue-id

The numeric ID of queue. An entry of ALSASeqSpecificQueueId is available as well.

Implements

QueueInfoExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl QueueInfo

pub const NONE: Option<&'static QueueInfo> = None

pub fn new() -> QueueInfo

Allocate and return an instance of QueueInfo.

Returns

An instance of QueueInfo.

Trait Implementations

impl Clone for QueueInfo

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for QueueInfo

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

Formats the value using the given formatter.

impl Default for QueueInfo

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for QueueInfo

type ParamSpec = ParamSpecObject

type SetValue = QueueInfo

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, QueueInfo>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for QueueInfo

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QueueInfo

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for QueueInfo

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for QueueInfo

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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<OT: ObjectType> PartialOrd<OT> for QueueInfo

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for QueueInfo

fn static_type() -> Type

Returns the type identifier of Self.
