Enum gstreamer::StructureChangeType

#[non_exhaustive]
pub enum StructureChangeType {
    Link,
    Unlink,
}

The type of a GST_MESSAGE_STRUCTURE_CHANGE.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Link

Pad linking is starting or done.

Unlink

Pad unlinking is starting or done.

Trait Implementations

Formats the value using the given formatter.

impl From<StructureChangeType> for Value

fn from(v: StructureChangeType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for StructureChangeType

type Checker = GenericValueTypeChecker<StructureChangeType>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for StructureChangeType

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for StructureChangeType

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

impl PartialEq for StructureChangeType

fn eq(&self, other: &StructureChangeType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for StructureChangeType

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for StructureChangeType
