Struct SubscribeData 

pub struct SubscribeData { /* private fields */ }

A GObject-derived object to express data for subscription between ports.

A SubscribeData is a GObject-derived object to express data for subscription between a pair of ports. The call of subscription_list() returns the list of data. The call of UserClientExt::operate_subscription() requires the instance of object.

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

Properties

dest

The address of destination.

Readable | Writeable

has-tstamp

Any event for the subscription has time stamp,

Readable | Writeable

is-exclusive

Whether the subscription can be changed by originator only,

Readable | Writeable

queue-id

The numeric ID of queue to deliver. One of ALSASeqSpecificQueueId is available as well as any numeric value.

Readable | Writeable

sender

The address of sender.

Readable | Writeable

tstamp-mode

The type of time stamp. This is effective when the has-tstamp property enabled.

Implements

SubscribeDataExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl SubscribeData

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

pub fn new() -> SubscribeData

Allocates and returns the instance of SubscribeData.

Returns

A SubscribeData.

Trait Implementations

impl Clone for SubscribeData

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 SubscribeData

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

Formats the value using the given formatter.

impl Default for SubscribeData

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for SubscribeData

type ParamSpec = ParamSpecObject

type SetValue = SubscribeData

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SubscribeData

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 SubscribeData

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 SubscribeData

type Parent = Object

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

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 SubscribeData

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 SubscribeData

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for SubscribeData
