Struct SDL_GPUIndexedIndirectDrawCommand 

#[repr(C)]
pub struct SDL_GPUIndexedIndirectDrawCommand {
    pub num_indices: Uint32,
    pub num_instances: Uint32,
    pub first_index: Uint32,
    pub vertex_offset: Sint32,
    pub first_instance: Uint32,
}

A structure specifying the parameters of an indexed indirect draw command.

Note that the first_vertex and first_instance parameters are NOT compatible with built-in vertex/instance ID variables in shaders (for example, SV_VertexID); GPU APIs and shader languages do not define these built-in variables consistently, so if your shader depends on them, the only way to keep behavior consistent and portable is to always pass 0 for the correlating parameter in the draw calls.

Availability

This struct is available since SDL 3.2.0.

Fields

num_indices: Uint32

The number of indices to draw per instance.

num_instances: Uint32

The number of instances to draw.

first_index: Uint32

The base index within the index buffer.

vertex_offset: Sint32

The value added to the vertex index before indexing into the vertex buffer.

first_instance: Uint32

The ID of the first instance to draw.

Trait Implementations

impl Clone for SDL_GPUIndexedIndirectDrawCommand

fn clone(&self) -> SDL_GPUIndexedIndirectDrawCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_GPUIndexedIndirectDrawCommand

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

Formats the value using the given formatter.

impl Default for SDL_GPUIndexedIndirectDrawCommand

fn default() -> SDL_GPUIndexedIndirectDrawCommand

Returns the “default value” for a type.

impl Hash for SDL_GPUIndexedIndirectDrawCommand

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 SDL_GPUIndexedIndirectDrawCommand

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