Struct vulkano::command_buffer::allocator::StandardCommandBufferAllocatorCreateInfo

pub struct StandardCommandBufferAllocatorCreateInfo {
    pub primary_buffer_count: usize,
    pub secondary_buffer_count: usize,
    pub _ne: NonExhaustive,
}

Parameters to create a new StandardCommandBufferAllocator.

Fields

primary_buffer_count: usize

How many primary command buffers should be allocated per pool.

Each time a thread allocates using some queue family index, and either no pools were initialized yet or all pools are full, a new pool is created for that thread and queue family combination. This option tells the allocator how many primary command buffers should be allocated for that pool. It always allocates exactly this many command buffers at once for the pool, as that is more performant than allocating them one-by-one. What this means is that you should make sure that this is not too large, so that you don’t end up wasting too much memory. You also don’t want this to be too low, because that on the other hand would mean that the pool would have to be reset more often, or that more pools would need to be created, depending on the lifetime of the command buffers.

The default value is 32.

secondary_buffer_count: usize

Same as primary_buffer_count except for secondary command buffers.

The default value is 0.

_ne: NonExhaustive

Trait Implementations

impl Clone for StandardCommandBufferAllocatorCreateInfo

fn clone(&self) -> StandardCommandBufferAllocatorCreateInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StandardCommandBufferAllocatorCreateInfo

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

Formats the value using the given formatter.

impl Default for StandardCommandBufferAllocatorCreateInfo

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for StandardCommandBufferAllocatorCreateInfo

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