Struct EventDataCtl 

pub struct EventDataCtl { /* private fields */ }

A boxed object to express data of control event.

A EventDataCtl is a boxed object to express data of control event. The instance of object is one of data properties in event.

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

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

Trait Implementations

impl Clone for EventDataCtl

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 EventDataCtl

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

Formats the value using the given formatter.

impl From<EventDataCtl> for Value

fn from(o: EventDataCtl) -> Self

Converts to this type from the input type.

impl HasParamSpec for EventDataCtl

type ParamSpec = ParamSpecBoxed

type SetValue = EventDataCtl

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for EventDataCtl

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 EventDataCtl

fn cmp(&self, other: &EventDataCtl) -> 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 EventDataCtl

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

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.
