Struct DeviceId 

pub struct DeviceId { /* private fields */ }

A boxed object to express the identifier of timer device.

A DeviceId is a boxed object to express the identifier of timer device. The identifier mainly consists of the class of timer device. The other members; the numeric ID of card, device, and subdevice are optional according to the class of timer device.

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

GLib type: Boxed type with copy-on-clone semantics.

Trait Implementations

impl Clone for DeviceId

fn clone(&self) -> Self

Copies the boxed type with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for DeviceId

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

Formats the value using the given formatter.

impl From<DeviceId> for Value

fn from(o: DeviceId) -> Self

Converts to this type from the input type.

impl HasParamSpec for DeviceId

type ParamSpec = ParamSpecBoxed

type SetValue = DeviceId

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

type BuilderFn = fn(&str) -> ParamSpecBoxedBuilder<'_, DeviceId>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for DeviceId

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

Feeds this value into the given Hasher.

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 DeviceId

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

This method returns an Ordering between self and other.

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,

impl PartialEq for DeviceId

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

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

This method returns an ordering between self and other values if one exists.

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.
