Statistics for a single collision kernel dispatch.

Fields

bytes_transferred: u64

Total bytes transferred (read + write) during the dispatch.

broadphase_pairs_tested: u64

Number of primitive pairs tested in the broadphase.

broadphase_hits: u64

Number of pairs that passed the broadphase (potential contacts).

narrowphase_queries: u64

Number of narrowphase GJK/SAT queries executed.

narrowphase_contacts: u64

Number of narrowphase queries that resulted in a contact.

elapsed_secs: f64

Elapsed wall-clock time for this dispatch in seconds.

Implementations

impl CollisionKernelStats

pub fn new() -> Self

Create a zero-initialised stats record.

pub fn broadphase_hit_rate(&self) -> f64

Broadphase hit-rate in [0, 1].

Returns 0.0 when no pairs were tested.

pub fn narrowphase_contact_rate(&self) -> f64

Narrowphase contact-rate in [0, 1].

Returns 0.0 when no narrowphase queries were executed.

pub fn bandwidth_gb_s(&self) -> f64

Estimated memory bandwidth in GB/s.

Returns 0.0 when elapsed time is zero.

pub fn pair_throughput(&self) -> f64

Pair throughput in pairs-per-second.

Returns 0.0 when elapsed time is zero.

pub fn accumulate(&mut self, other: &CollisionKernelStats)

Accumulate another stats record into this one.

Trait Implementations

impl Clone for CollisionKernelStats

fn clone(&self) -> CollisionKernelStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CollisionKernelStats

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

Formats the value using the given formatter.

impl Default for CollisionKernelStats

fn default() -> CollisionKernelStats

Returns the “default value” for a type.
