Struct IndirectArgs 

pub struct IndirectArgs {
    pub buffer: Arc<Buffer>,
    pub offset: u64,
}

Handle + offset identifying where in GPU memory the [u32; 3] workgroup count lives.

Fields

buffer: Arc<Buffer>

GPU buffer containing the workgroup count at the given byte offset.

offset: u64

Byte offset within buffer. Must be 4-byte aligned per wgpu’s contract.

Implementations

impl IndirectArgs

pub fn from_handle( handle: &GpuBufferHandle, offset: u64, ) -> Result<Self, BackendError>

Build an IndirectArgs from a GpuBufferHandle + offset.

Errors

Returns a BackendError when:

• offset is not 4-byte aligned (wgpu rejects unaligned indirect dispatches).
• offset + INDIRECT_ARGS_BYTES would exceed the buffer’s byte length.
• The underlying buffer does not carry wgpu::BufferUsages::INDIRECT.
