Enum ValueRangeConstraint

pub enum ValueRangeConstraint<T> {
    Bare(T),
    Constraint(ResolvedValueRangeConstraint<T>),
}

A bare value or constraint specifying a range of accepted values.

W3C Spec Compliance

There exists no direct corresponding type in the W3C “Media Capture and Streams” spec, since the ValueConstraint<T> type aims to be a generalization over multiple types in the spec.

Rust	W3C
ValueRangeConstraint<u64>	ConstrainULong
ValueRangeConstraint<f64>	ConstrainDouble

Variants

Bare(T)

A bare-valued media track constraint.

Constraint(ResolvedValueRangeConstraint<T>)

A fully-qualified media track constraint.

Implementations

impl<T> ValueRangeConstraint<T>

where T: Clone,

pub fn to_resolved( &self, strategy: MediaTrackConstraintResolutionStrategy, ) -> ResolvedValueRangeConstraint<T>

Returns a resolved representation of the constraint with bare values resolved to fully-qualified constraints.

pub fn into_resolved( self, strategy: MediaTrackConstraintResolutionStrategy, ) -> ResolvedValueRangeConstraint<T>

Consumes the constraint, returning a resolved representation of the constraint with bare values resolved to fully-qualified constraints.

impl<T> ValueRangeConstraint<T>

pub fn is_empty(&self) -> bool

Returns true if self is empty, otherwise false.

Trait Implementations

impl<T: Clone> Clone for ValueRangeConstraint<T>

fn clone(&self) -> ValueRangeConstraint<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ValueRangeConstraint<T>

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

Formats the value using the given formatter.

impl<T> Default for ValueRangeConstraint<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for ValueRangeConstraint<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<ResolvedValueRangeConstraint<T>> for ValueRangeConstraint<T>

fn from(constraint: ResolvedValueRangeConstraint<T>) -> Self

Converts to this type from the input type.

impl<T> From<T> for ValueRangeConstraint<T>

fn from(bare: T) -> Self

Converts to this type from the input type.

impl From<ValueRangeConstraint<f64>> for MediaTrackConstraint

fn from(constraint: ValueRangeConstraint<f64>) -> Self

Converts to this type from the input type.

impl From<ValueRangeConstraint<u64>> for MediaTrackConstraint

fn from(constraint: ValueRangeConstraint<u64>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for ValueRangeConstraint<T>

fn eq(&self, other: &ValueRangeConstraint<T>) -> 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<T> Serialize for ValueRangeConstraint<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
