Struct SystemInfo 

pub struct SystemInfo { /* private fields */ }

A GObject-derived object to express information of ALSA Sequencer.

A SystemInfo is a GObject-derived object to express information of ALSA Sequencer. The call of system_info() returns the instance of object.

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

Implements

SystemInfoExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl SystemInfo

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

Trait Implementations

impl Clone for SystemInfo

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 SystemInfo

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

Formats the value using the given formatter.

impl HasParamSpec for SystemInfo

type ParamSpec = ParamSpecObject

type SetValue = SystemInfo

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SystemInfo

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 SystemInfo

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 SystemInfo

type Parent = Object

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

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 SystemInfo

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 SystemInfo

fn static_type() -> Type

Returns the type identifier of Self.
