Implementations

impl ParamSpecFraction

pub fn as_ptr(&self) -> *mut GstParamSpecFraction

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GstParamSpecFraction, ) -> &'a Self

Borrows the underlying C value.

impl ParamSpecFraction

pub fn builder(name: &str) -> ParamSpecFractionBuilder<'_>

unsafe fn new_unchecked<'a>( name: &str, nick: impl Into<Option<&'a str>>, blurb: impl Into<Option<&'a str>>, min: Fraction, max: Fraction, default: Fraction, flags: ParamFlags, ) -> ParamSpec

pub fn minimum(&self) -> Fraction

pub fn maximum(&self) -> Fraction

pub fn default_value(&self) -> Fraction

pub fn upcast(self) -> ParamSpec

pub fn upcast_ref(&self) -> &ParamSpec

Methods from Deref<Target = ParamSpec>

pub fn as_ptr(&self) -> *mut GParamSpec

Return the inner pointer to the underlying C value.

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: ParamSpecType,

pub fn type_(&self) -> Type

pub fn is<T>(&self) -> bool

where T: StaticType,

pub fn value_type(&self) -> Type

pub fn owner_type(&self) -> Type

pub fn flags(&self) -> ParamFlags

pub fn blurb(&self) -> Option<&str>

pub fn default_value(&self) -> &Value

pub fn name<'a>(&self) -> &'a str

pub fn name_quark(&self) -> Quark

pub fn nick(&self) -> &str

pub fn redirect_target(&self) -> Option<ParamSpec>

Trait Implementations

impl Clone for ParamSpecFraction

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.

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

Performs copy-assignment from source.

impl Debug for ParamSpecFraction

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

Formats the value using the given formatter.

impl Deref for ParamSpecFraction

type Target = ParamSpec

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<ParamSpecFraction> for Value

fn from(s: ParamSpecFraction) -> Self

Converts to this type from the input type.

impl HasParamSpec for ParamSpecFraction

type ParamSpec = ParamSpecBoxed

type SetValue = ParamSpecFraction

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ParamSpecFraction

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 ParamSpecFraction

fn cmp(&self, other: &ParamSpecFraction) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ParamSpecFraction

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

impl PartialOrd for ParamSpecFraction

fn partial_cmp(&self, other: &ParamSpecFraction) -> 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.

impl StaticType for ParamSpecFraction

fn static_type() -> Type

Returns the type identifier of Self.
