Struct ClientPool 

pub struct ClientPool { /* private fields */ }

A GObject-derived object to express information of pool owned by client.

A ClientPool is a GObject-derived object to express information of pool owned by client. The pool consists of a batch of cells to store message contents in kernel space. The call of client_pool() returns the instance of object. The call of UserClientExt::set_pool()) and UserClientExtManual::pool() require the instance of object.

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

Properties

client-id

The numeric ID of client. One of SpecificClientId is available as well as any numeric value.

Readable

input-free

The current number of free cells in memory pool for input direction.

Readable | Writeable

input-pool

The total number of cells in memory pool for input direction. The client dequeue any event from the pool when the event is copied from the output memory pool of source client.

Readable | Writeable

output-free

The current number of free cells in memory pool for output direction.

Readable | Writeable

output-pool

The total number of cells in memory pool for output direction. The client enqueue any event into the pool at scheduling, then the event is copied to input memory pool of destination client.

Readable | Writeable

output-room

The number of cells in memory pool for output direction as threshold for writable condition at the result of poll(2). The property is useless for UserClient since it doesn’t perform poll(2) to check writable or not.

Implements

ClientPoolExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl ClientPool

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

pub fn new() -> ClientPool

Trait Implementations

impl Clone for ClientPool

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 ClientPool

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

Formats the value using the given formatter.

impl Default for ClientPool

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for ClientPool

type ParamSpec = ParamSpecObject

type SetValue = ClientPool

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ClientPool

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 ClientPool

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 ClientPool

type Parent = Object

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

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 ClientPool

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 ClientPool

fn static_type() -> Type

Returns the type identifier of Self.
