Implementations

impl CudaMegakernelPlanCacheKey

pub fn new( graph_layout_hash: u64, analysis_kind: CudaMegakernelAnalysisKind, device: CudaMegakernelDeviceKey, frontier_density: f64, memory_pressure_bps: u32, readback_bytes: u64, launch_pressure_bps: u32, fusion_pressure: f64, ) -> Self

Build a cache key from stable identity fields and runtime pressure.

Trait Implementations

impl Clone for CudaMegakernelPlanCacheKey

fn clone(&self) -> CudaMegakernelPlanCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CudaMegakernelPlanCacheKey

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

Formats the value using the given formatter.

impl Hash for CudaMegakernelPlanCacheKey

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 Ord for CudaMegakernelPlanCacheKey

fn cmp(&self, other: &CudaMegakernelPlanCacheKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CudaMegakernelPlanCacheKey

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

impl PartialOrd for CudaMegakernelPlanCacheKey

fn partial_cmp(&self, other: &CudaMegakernelPlanCacheKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
