Struct LaunchBuilder 

pub struct LaunchBuilder<'k> { /* private fields */ }

Builder produced by Kernel::launch.

Implementations

impl<'k> LaunchBuilder<'k>

pub fn grid(self, grid: impl Into<Dim3>) -> Self

Set the grid dimensions (number of thread blocks).

pub fn block(self, block: impl Into<Dim3>) -> Self

Set the block dimensions (threads per block).

pub fn shared_mem_bytes(self, bytes: usize) -> Self

Reserve bytes of dynamic shared memory per block.

pub fn stream(self, stream: &'k Stream) -> Self

Enqueue on stream instead of the default stream.

pub fn arg<K: KernelArg>(self, arg: K) -> Self

Append arg to the kernel argument list. Arguments are passed positionally in the order they are added.

pub unsafe fn launch(self) -> Result<()>

Enqueue the kernel.

Safety

Same rules as [baracuda_driver::LaunchBuilder::launch]: argument types and order must match the kernel’s C signature, referenced device memory must stay valid for the duration of device execution, and grid/block dims must be within device limits.

pub unsafe fn launch_cooperative(self) -> Result<()>

Launch as a cooperative kernel — grid-wide sync via cooperative_groups::this_grid(). All blocks must fit resident on the device simultaneously; use crate::Kernel::max_active_blocks_per_multiprocessor to size the grid.

Safety

Same as launch plus the kernel must be compiled with cooperative-groups support.

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

Formats the value using the given formatter.
