Struct CudaDevice

pub struct CudaDevice(/* private fields */);

Export the CudaDevice type for convenience: often an explicit dependency on the kn_cuda_sys crate is not needed. A cuda device index.

This crate tries to eliminate the global “current device” cuda state: Every cuda call that depends on the device should be preceded by device.switch_to(), which corresponds to cudaSetDevice.

Trait Implementations

impl Clone for CudaDevice

fn clone(&self) -> CudaDevice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CudaDevice

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

Formats the value using the given formatter.

impl Hash for CudaDevice

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CudaDevice

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