Struct GpuState 

pub struct GpuState { /* private fields */ }

Per-module GPU state: device, queue, and resource tables.

Implementations

impl GpuState

pub fn create_buffer(&mut self, size: u64, usage_bits: u32) -> GpuHandle

Create a GPU buffer with the given size and usage flags. Returns a handle, or 0 on failure.

pub fn create_texture(&mut self, width: u32, height: u32) -> GpuHandle

Create a 2D RGBA8 texture. Returns a handle, or 0 on failure.

pub fn create_shader(&mut self, source: &str) -> GpuHandle

Compile a WGSL shader module. Returns a handle, or 0 on failure.

pub fn create_render_pipeline( &mut self, shader_handle: GpuHandle, vertex_entry: &str, fragment_entry: &str, ) -> GpuHandle

Create a render pipeline from a shader handle. vertex_entry and fragment_entry name the WGSL entry points. Returns a handle, or 0 if the shader handle is invalid.

pub fn create_compute_pipeline( &mut self, shader_handle: GpuHandle, entry_point: &str, ) -> GpuHandle

Create a compute pipeline from a shader handle.

pub fn write_buffer(&self, handle: GpuHandle, offset: u64, data: &[u8]) -> bool

Write data to a GPU buffer from guest memory.

pub fn draw( &self, pipeline_handle: GpuHandle, target_texture: GpuHandle, vertex_count: u32, instance_count: u32, ) -> bool

Submit a render pass that draws vertex_count vertices using the given pipeline, targeting a texture.

pub fn dispatch_compute( &self, pipeline_handle: GpuHandle, workgroups_x: u32, workgroups_y: u32, workgroups_z: u32, ) -> bool

Submit a compute dispatch.

pub fn destroy_buffer(&mut self, handle: GpuHandle) -> bool

Destroy a buffer resource.

pub fn destroy_texture(&mut self, handle: GpuHandle) -> bool

Destroy a texture resource.
