Struct Request

pub struct Request {
    pub size: u64,
    pub align_mask: u64,
    pub usage: UsageFlags,
    pub memory_types: u32,
}

Memory request for allocator.

Fields

size: u64

Minimal size of memory block required. Returned block may have larger size, use MemoryBlock::size to learn actual size of returned block.

align_mask: u64

Minimal alignment mask required. Returned block may have larger alignment, use MemoryBlock::align to learn actual alignment of returned block.

usage: UsageFlags

Intended memory usage. Returned block may support additional usages, use MemoryBlock::props to learn memory properties of returned block.

memory_types: u32

Bitset for memory types. Returned block will be from memory type corresponding to one of set bits, use MemoryBlock::memory_type to learn memory type index of returned block.

Trait Implementations

impl Clone for Request

fn clone(&self) -> Request

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Request

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

Formats the value using the given formatter.

impl Hash for Request

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

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 Request

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