Struct krnl::device::Features

pub struct Features { /* private fields */ }

Features supported by a device.

See DeviceInfo::features().

Kernels can not be compiled unless the device supports all features used.

Use features to specialize or provide a more helpful error message:

if features.contains(Features::INT8 | Features::BUFFER8) {
    /* u8 impl */
} else {
    /* fallback */
}

Trait Implementations

impl BitOr for Features

type Output = Features

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for Features

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for Features

fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl PartialEq for Features

fn eq(&self, other: &Features) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
