Enum CoherencyState 

pub enum CoherencyState {
    HostOnly,
    DeviceOnly,
    Synced,
    HostDirty,
    DeviceDirty,
}

Coherency state for host-device memory

Variants

HostOnly

Data only exists on host

DeviceOnly

Data only exists on device

Synced

Host and device are synchronized (identical)

HostDirty

Host has been modified, device is stale

DeviceDirty

Device has been modified, host is stale

Implementations

impl CoherencyState

pub fn host_is_current(&self) -> bool

Check if host data is current

pub fn device_is_current(&self) -> bool

Check if device data is current

pub fn needs_sync(&self) -> bool

Check if synchronization is needed

Trait Implementations

impl Clone for CoherencyState

fn clone(&self) -> CoherencyState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoherencyState

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

Formats the value using the given formatter.

impl PartialEq for CoherencyState

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