Struct PlanKey 

pub struct PlanKey {
    pub op_kind: OpKind,
    pub modes_hash: u64,
    pub extents_hash: u64,
    pub alignment: u32,
    pub compute_desc_tag: u32,
    pub dtype_tag: &'static str,
    pub algo: i32,
}

Hashable plan key. Modes / extents arrive pre-hashed (u64) so the key remains Copy + Eq.

Fields

op_kind: OpKind

modes_hash: u64

extents_hash: u64

alignment: u32

compute_desc_tag: u32

dtype_tag: &'static str

algo: i32

0 means “default algorithm”. Autotune writes the chosen cutensorAlgo_t as i32 here so autotuned plans get their own cache slot.

Trait Implementations

impl Clone for PlanKey

fn clone(&self) -> PlanKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlanKey

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

Formats the value using the given formatter.

impl Hash for PlanKey

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 PlanKey

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