Enum Scalar 

#[non_exhaustive]
pub enum Scalar<'a, T> {
    Host(&'a T),
    Device(DeviceScalar<T>),
}

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.

Host(&'a T)

Device(DeviceScalar<T>)

Implementations

impl<'a, T> Scalar<'a, T>

pub const fn host(value: &'a T) -> Self

pub const unsafe fn device(ptr: DevicePtr) -> Self

Creates a device-resident scalar from a raw device pointer.

Safety

ptr must point to a valid device allocation containing a T for every cuSPARSE operation using this scalar.

Trait Implementations

impl<'a, T: Clone> Clone for Scalar<'a, T>

fn clone(&self) -> Scalar<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Copy> Copy for Scalar<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> From<&'a T> for Scalar<'a, T>

fn from(value: &'a T) -> Self

Converts to this type from the input type.

impl<T> From<DeviceScalar<T>> for Scalar<'_, T>

fn from(value: DeviceScalar<T>) -> Self
