Enum accel::memory::MemoryType

pub enum MemoryType {
    Host,
    PageLocked,
    Device,
    Array,
}

Memory type

Because of unified addressing, we can get the memory type after casted into slice:

• DeviceMemory

let mem = DeviceMemory::<i32>::zeros(&ctx, 12);
let sl = mem.as_slice();
assert_eq!(sl.memory_type(), MemoryType::Device);

• PageLockedMemory

let mem = PageLockedMemory::<i32>::zeros(&ctx, 12);
let sl = mem.as_slice();
assert_eq!(sl.memory_type(), MemoryType::PageLocked);

• RegisteredMemory
  • Be sure that RegisteredMemory and PageLockedMemory are indistinguishable

let mut a = vec![0_i32; 12];
let mem = RegisteredMemory::<i32>::new(&ctx, &mut a);
let sl = mem.as_slice();
assert_eq!(sl.memory_type(), MemoryType::PageLocked);

• Array cannot be casted into a slice

impl PartialOrd<MemoryType> for MemoryType

fn partial_cmp(&self, other: &MemoryType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
