Struct AuxCounts 

pub struct AuxCounts {
    pub presented: u64,
    pub skipped: u64,
}

What AuxTarget::present did with the calls it was given, since attach.

The witness a cost measurement of this surface needs (ADR-0172). Every arm of the present path that returns without reaching queue.present returns the same Ok(()) a successful present does, so a surface that was occluded for a whole run and one that presented every frame produce the same log and the same frame rate. presented is what separates them; a measurement reading zero cost against a zero present count has measured nothing.

presented + skipped is the number of calls the target received, which is what lets a caller reconcile its own totals: whatever it decimated, plus these two, is the frames it ran with this target attached.

Fields

presented: u64

Calls that reached this surface’s own queue.present.

skipped: u64

Calls that returned without presenting — the surface had no texture to give, or refused validation.

Trait Implementations

impl Clone for AuxCounts

fn clone(&self) -> AuxCounts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuxCounts

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

Formats the value using the given formatter.

impl Default for AuxCounts

fn default() -> AuxCounts

Returns the “default value” for a type.

impl PartialEq for AuxCounts

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