Struct PrecisionSchedule 

pub struct PrecisionSchedule { /* private fields */ }

2026-09-25: Per-(layer, role) precision schedule: one dtype per role, a global default, and a set of sensitive layers with their own dtype.

Implementations

impl PrecisionSchedule

pub fn build( router_dtype: Dtype, lm_head_dtype: Dtype, sensitive_block_indices: &[u16], sensitive_block_dtype: Dtype, default_dtype: Dtype, ) -> Self

2026-09-25: Build a schedule from:

• router_dtype: dtype for the MoE gate
• lm_head_dtype: dtype for the final unembedding
• sensitive_block_dtype + sensitive_block_indices: the dtype for the weight tensors of the listed layers
• default_dtype: the global default

The other roles’ dtypes are Inherit.

pub fn dtype_for(&self, layer_idx: Option<u16>, role: Role) -> Dtype

2026-09-25: Resolve the target dtype for a tensor. layer_idx = None is for non-layer tensors (embedding, lm_head, final norm). Lookup order, skipping any step that yields Inherit:

1. Sensitive-layer dtype (Attention, Expert and SharedExpert only)
2. Per-role dtype
3. Global default

pub fn has_any_override(&self) -> bool

2026-09-25: True iff some lookup can return a dtype other than Inherit. The qwen35 loader logs the schedule when it is.

Trait Implementations

impl Clone for PrecisionSchedule

fn clone(&self) -> PrecisionSchedule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrecisionSchedule

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

Formats the value using the given formatter.

impl Default for PrecisionSchedule

fn default() -> Self

2026-09-25: Empty schedule: every lookup returns Inherit.
