Detailed Description

Descriptor binding description for RootSignature and Descriptor Storage creation. Description place in array determines binding index that this lane maps to. e.g. bindings[1] means on HLSL side this results in [[vk::binding(0,1)]]. All the bindings in Descriptor Storage are unbounded, array of these structures determine the presence and order of the bindings.

 
struct DescriptorBindingDesc {
    wis::DescriptorType binding_type; 
    uint32_t binding_space; 
    uint32_t space_overlap_count;
    uint32_t binding_count;
};

Public Attributes
wis::DescriptorType	binding_type
	Binding type. Must be unique in array.

uint32_t	binding_space
	Binding space number in HLSL.

uint32_t	space_overlap_count
	Number of consecutive spaces this binding occupies. e.g. for binding_space = 1 and space_overlap_count = 3, HLSL binding will be :register(x0,space1), register(x0,space2), register(x0,space3) This is useful for binding multiple resource types to the same register array in HLSL.

uint32_t	binding_count
	How many bindings should be allocated. Affects only the count of descriptors allocated in the descriptor heap, Root Signature always receives unbounded array with max amount of 4096 registers.
