Enum DsaSelectLaunch 

pub enum DsaSelectLaunch {
    Exact,
    Ceiling {
        max_pools: usize,
    },
}

2026-09-25: How a pass is launched: exactly, or at the context ceiling so one graph serves any length.

Ceiling requires DsaSelectInputs::geom_dev and q_rows == 1 (select_tokens refuses otherwise). The kernels read their row strides (out/valid_cand stride P, selected stride select_k) from the same device geometry, which is sound only because every r * stride is then 0 * stride.

Variants

Exact

2026-09-25: This step’s exact grid, from the host geometry.

Ceiling

2026-09-25: Grid and shared memory fixed at max_pools; live extents come from geom_dev.

Fields

max_pools: usize

Trait Implementations

impl Clone for DsaSelectLaunch

fn clone(&self) -> DsaSelectLaunch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DsaSelectLaunch

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

Formats the value using the given formatter.

impl PartialEq for DsaSelectLaunch

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