Struct BindingSetFingerprint 

pub struct BindingSetFingerprint {
    pub slots: Vec<(u32, BindingRole, usize)>,
}

Stable fingerprint of a binding set’s layout - the parts that determine whether two BindingPlans can share a backend bind group layout / descriptor set.

Two plans with the same BindingSetFingerprint can reuse the same portable::BindGroupLayout or native descriptor set across consecutive dispatches, skipping the layout-rebind cost. The hot-path perf snapshot puts binding rebind at ~20% of warm dispatch time on attention/softmax/reduce shapes.

Layout (this fingerprint) is distinct from contents (which program_vsa_fingerprint covers) - two dispatches of the same kernel on different input buffers share a layout fingerprint but differ in their content fingerprint.

Fields

slots: Vec<(u32, BindingRole, usize)>

Per-binding layout slot: (binding_index, role, element_size). Ordered by binding_index for deterministic equality.

Implementations

impl BindingSetFingerprint

pub fn from_plan(plan: &BindingPlan) -> Self

Derive the layout fingerprint from a BindingPlan. Stable across runs and across machines (no random salts).

Trait Implementations

impl Clone for BindingSetFingerprint

fn clone(&self) -> BindingSetFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingSetFingerprint

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

Formats the value using the given formatter.

impl Eq for BindingSetFingerprint

impl Hash for BindingSetFingerprint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BindingSetFingerprint

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