Struct ElemInfoEnumerated 

pub struct ElemInfoEnumerated { /* private fields */ }

An object to express information for enumerated type of element.

A GObject::Object derived object class for enumerated type of element.

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

Properties

labels

The list of indexed labels for the element. There is limitation that:

• The length of label including terminator should be within 64 bytes.
• The total length of labels including terminators should be within (64 * 1024) bytes.

Readable | Writeable

ElemInfoCommon

access

The access permission for the element with ElemAccessFlag.

Readable | Writeable

elem-id

The identifier of element.

Readable

elem-type

The type of element, one of ElemType.

Readable | Writeable | Construct Only

owner

The value of PID for process to own the element.

Readable

ElemInfoSingleArray

value-count

The count of elements in value array of the element.

Implements

ElemInfoEnumeratedExt, ElemInfoCommonExt, ElemInfoSingleArrayExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl ElemInfoEnumerated

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

pub fn new() -> ElemInfoEnumerated

Allocate and return an instance of ElemInfoEnumerated.

Returns

An instance of ElemInfoEnumerated.

Trait Implementations

impl Clone for ElemInfoEnumerated

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 ElemInfoEnumerated

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

Formats the value using the given formatter.

impl Default for ElemInfoEnumerated

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for ElemInfoEnumerated

type ParamSpec = ParamSpecObject

type SetValue = ElemInfoEnumerated

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ElemInfoEnumerated

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 ElemInfoEnumerated

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 ElemInfoEnumerated

type Parent = Object

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

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 ElemInfoEnumerated

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 ElemInfoEnumerated

fn static_type() -> Type

Returns the type identifier of Self.
