Struct DisplayId 

#[repr(C)]
pub struct DisplayId {
    pub value: u64,
}

Unique identifier for a display device attached to the system.

[fuchsia.hardware.display.types/INVALID_DISP_ID] represents an invalid value.

Values are unique within a [fuchsia.hardware.display/Controller] connection. An external display will be associated with different display ID values if it is disconnected and reconnected.

A display device may be identified by different values across boot cycles or across different Controller connections. Software that needs to identify displays (for example, to honor display-specific preferences) should use [fuchsia.hardware.display/Info] identifiers, not display IDs.

This type is not related to the VESA DisplayID standard.

Fields

Whether the conversion from W to Self is equivalent to copying the raw bytes of W.

fn from_wire(wire: DisplayId) -> DisplayId

Converts the given owned value to this type.

impl FromWireRef<DisplayId> for DisplayId

fn from_wire_ref(wire: &DisplayId) -> DisplayId

impl Ord for DisplayId

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

impl PartialEq for DisplayId

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