Struct BindTarget

pub struct BindTarget {
    pub space: u8,
    pub register: u32,
    pub binding_array_size: Option<u32>,
    pub dynamic_storage_buffer_offsets_index: Option<u32>,
    pub restrict_indexing: bool,
}

Direct3D 12 binding information for a global variable.

This type provides the HLSL-specific information Naga needs to declare and access an HLSL global variable that cannot be derived from the Module itself.

An HLSL global variable declaration includes details that the Direct3D API will use to refer to it. For example:

RWByteAddressBuffer s_sasm : register(u0, space2);

This defines a global s_sasm that a Direct3D root signature would refer to as register 0 in register space 2 in a UAV descriptor range. Naga can infer the register’s descriptor range type from the variable’s address class (writable Storage variables are implemented by Direct3D Unordered Access Views, the u register type), but the register number and register space must be supplied by the user.

The back::hlsl::Options structure provides BindTargets for various situations in which Naga may need to generate an HLSL global variable, like binding_map for Naga global variables, or push_constants_target for a module’s sole PushConstant variable. See those fields’ documentation for details.

Fields

space: u8

register: u32

For regular bindings this is the register number.

For sampler bindings, this is the index to use into the bind group’s sampler index buffer.

binding_array_size: Option<u32>

If the binding is an unsized binding array, this overrides the size.

dynamic_storage_buffer_offsets_index: Option<u32>

This is the index in the buffer at Options::dynamic_storage_buffer_offsets_targets.

restrict_indexing: bool

This is a hint that we need to restrict indexing of vectors, matrices and arrays.

If Options::restrict_indexing is also true, we will restrict indexing.

Trait Implementations

impl Clone for BindTarget

fn clone(&self) -> BindTarget

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BindTarget

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

Formats the value using the given formatter.

impl Default for BindTarget

fn default() -> BindTarget

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BindTarget

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for BindTarget

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 BindTarget

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

impl Serialize for BindTarget

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
