Struct amethyst_rendy::rendy::memory::DedicatedAllocator

[+] Show declaration

pub struct DedicatedAllocator { /* fields omitted */ }

[−] Expand description

Dedicated memory allocator that uses memory object per allocation requested.

This allocator suites best huge allocations. From 32 MiB when GPU has 4-8 GiB memory total.

Heaps use this allocator when none of sub-allocators bound to the memory type can handle size required. TODO: Check if resource prefers dedicated memory.

Methods

impl DedicatedAllocator[−]

pub fn properties_required() -> Properties[−]

Get properties required by the allocator.

pub fn new(
    memory_type: MemoryTypeId,
    memory_properties: Properties
) -> DedicatedAllocator[−]

Create new LinearAllocator for memory_type with memory_properties specified
