Struct NodeHints 

pub struct NodeHints {
    pub fp16_eligible: bool,
    pub compile_time_constant: bool,
}

Per-node hint bits derived from the foundation analyses.

Callers populate this from the substrate they already have: PrecisionHints::lookup(digest) for fp16_eligible, the F1 vsa_specialization_key for compile_time_constant. The cost helper does not compute these - it only consumes them.

Fields

fp16_eligible: bool

Foundation precision_hint analysis flagged this node as representable in F16. The extractor will prefer this node when the device profile reports tensor-core support.

compile_time_constant: bool

F1 specialization detected this node’s value as a compile-time constant. Reserved for the F3 dtype-spec wiring; not yet consumed by this helper.

Trait Implementations

impl Clone for NodeHints

fn clone(&self) -> NodeHints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeHints

impl Debug for NodeHints

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

Formats the value using the given formatter.

impl Default for NodeHints

fn default() -> NodeHints

Returns the “default value” for a type.

impl Eq for NodeHints

impl PartialEq for NodeHints

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