Usage flags for allocator

@warning All flags except USAGE_DEFAULT are experimental.

@warning For the OpenCL allocator, USAGE_ALLOCATE_SHARED_MEMORY depends on OpenCV’s optional, experimental integration with OpenCL SVM. To enable this integration, build OpenCV using the WITH_OPENCL_SVM=ON CMake option and, at runtime, call cv::ocl::Context::getDefault().setUseSVM(true); or similar code. Note that SVM is incompatible with OpenCL 1.x.

Trait Implementations

impl Clone for UMatUsageFlags

fn clone(&self) -> UMatUsageFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UMatUsageFlags

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

Formats the value using the given formatter.

impl From<UMatUsageFlags> for i32

fn from(v: UMatUsageFlags) -> Self

Converts to this type from the input type.

impl PartialEq for UMatUsageFlags

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

impl TryFrom<i32> for UMatUsageFlags

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
