Struct MediaEntityDesc 

pub struct MediaEntityDesc {
    pub id: EntityId,
    pub name: String,
    pub type: MediaEntityFunctions,
    pub flags: MediaEntityFlags,
    pub pads: usize,
    pub links: usize,
}

Fields

id: EntityId

Entity ID, set by the application. When the ID is or’ed with MEDIA_ENT_ID_FLAG_NEXT, the driver clears the flag and returns the first entity with a larger ID. Do not expect that the ID will always be the same for each instance of the device. In other words, do not hardcode entity IDs in an application.

name: String

Entity name. This name must be unique within the media topology.

type: MediaEntityFunctions

Entity type.

flags: MediaEntityFlags

Entity flags.

pads: usize

Number of pads

links: usize

Total number of outbound links. Inbound links are not counted in this field.

Trait Implementations

impl Clone for MediaEntityDesc

fn clone(&self) -> MediaEntityDesc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MediaEntityDesc

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MediaEntityDesc

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<media_entity_desc> for MediaEntityDesc

fn from(desc: media_entity_desc) -> Self

Converts to this type from the input type.

impl Ord for MediaEntityDesc

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

Restrict a value to a certain interval.

impl PartialEq for MediaEntityDesc

fn eq(&self, other: &MediaEntityDesc) -> 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 MediaEntityDesc

fn partial_cmp(&self, other: &MediaEntityDesc) -> 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 Serialize for MediaEntityDesc

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
