operator==()

bool Diligent::SparseResourceProperties::operator== ( const SparseResourceProperties & RHS ) const

inlineconstexpr

Comparison operator tests if two structures are equivalent.

Parameters

[in]

RHS

- reference to the structure to perform comparison with

Returns

• True if all members of the two structures are equal.
• False otherwise.

StandardBlockSize

Uint32 Diligent::SparseResourceProperties::StandardBlockSize = 0

Size of the standard sparse memory block in bytes.

In Direct3D11, Direct3D12 and Vulkan this is 64Kb. In Metal it is implementation-defined.

Query standard block support using IRenderDevice::GetSparseTextureFormatInfo() and check SparseTextureFormatInfo::Flags for SPARSE_TEXTURE_FLAG_NONSTANDARD_BLOCK_SIZE flag.
