Struct GdnFlags 

pub struct GdnFlags {
    pub h_f16: bool,
    pub h_f16_pool: bool,
    pub fused_norm: bool,
    pub batched_recurrent: bool,
    pub exact_verify: bool,
}

Fields

h_f16: bool

2026-09-25: --ssm-h-dtype f16 (or f16-pool): store the GDN decode h-state as FP16.

h_f16_pool: bool

2026-09-25: --ssm-h-dtype f16-pool: also size the h pools at 2 bytes per element. Always set together with h_f16 (a narrow pool holding FP32 would be an out-of-bounds write).

fused_norm: bool

2026-09-25: --gdn-fused-norm: fused GDN output-norm decode kernel.

batched_recurrent: bool

2026-09-25: --ssm-batched-recurrent: one strided recurrent launch per batch.

exact_verify: bool

2026-09-25: --exact-verify: MTP verify runs the sequential-decode-exact per-token GDN/SSM chain instead of the WY-chunkwise and fused BF16-conv arms. Off by default. It makes only the GDN/SSM verify chain exact; the FFN and attention projections still pick kernels by row count.

Implementations

impl GdnFlags

pub fn verify_exact_active(self) -> bool

2026-09-25: Whether the MTP-verify pass runs the exact chain: exact_verify. Pure, so tests need not touch the process-wide cell.

2026-10-01: Also under an FP16 h-state, which runs the FP16 twins of the exact chain (gdn_exact_chain_f16_{K}); a kernel set without them refuses the serve at the boot audit (carry.rs).

Trait Implementations

impl Clone for GdnFlags

fn clone(&self) -> GdnFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GdnFlags

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

Formats the value using the given formatter.

impl PartialEq for GdnFlags

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