Struct ResidentGraphReuseTelemetry 

pub struct ResidentGraphReuseTelemetry {
    pub cold_uploads: u64,
    pub warm_reuses: u64,
    pub upload_bytes: u64,
    pub avoided_upload_bytes: u64,
}

Cold-upload and warm-reuse counters for a retained resident graph.

Fields

cold_uploads: u64

Resident graph cache misses that required host-to-device upload.

warm_reuses: u64

Resident graph cache hits that reused an already-live device graph.

upload_bytes: u64

Graph bytes uploaded by cold misses.

avoided_upload_bytes: u64

Graph upload bytes avoided by warm reuses.

Implementations

impl ResidentGraphReuseTelemetry

pub const fn from_counters( cold_uploads: u64, warm_reuses: u64, upload_bytes: u64, avoided_upload_bytes: u64, ) -> Self

Build telemetry from explicit counters.

pub const fn cold_upload(upload_bytes: u64) -> Self

Telemetry for one cold graph upload.

pub const fn warm_reuse(avoided_upload_bytes: u64) -> Self

Telemetry for one warm resident graph reuse.

pub const fn is_empty(self) -> bool

Return true when no resident-graph reuse event has been recorded.

pub fn checked_add( self, rhs: Self, ) -> Result<Self, ResidentGraphReuseTelemetryError>

Merge two telemetry snapshots with checked arithmetic.

pub fn checked_delta_since( self, earlier: Self, ) -> Result<Self, ResidentGraphReuseTelemetryError>

Return the telemetry delta observed after an earlier monotonic snapshot.

pub fn record_cold_upload( &mut self, upload_bytes: u64, ) -> Result<(), ResidentGraphReuseTelemetryError>

Record one cold graph upload in place.

pub fn record_warm_reuse( &mut self, avoided_upload_bytes: u64, ) -> Result<(), ResidentGraphReuseTelemetryError>

Record one warm resident graph reuse in place.

pub fn record_cold_uploads( &mut self, cold_uploads: u64, upload_bytes: u64, ) -> Result<(), ResidentGraphReuseTelemetryError>

Record several cold graph uploads in place.

pub fn record_warm_reuses( &mut self, warm_reuses: u64, avoided_upload_bytes: u64, ) -> Result<(), ResidentGraphReuseTelemetryError>

Record several warm resident graph reuses in place.

Trait Implementations

impl Clone for ResidentGraphReuseTelemetry

fn clone(&self) -> ResidentGraphReuseTelemetry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResidentGraphReuseTelemetry

impl Debug for ResidentGraphReuseTelemetry

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

Formats the value using the given formatter.

impl Default for ResidentGraphReuseTelemetry

fn default() -> ResidentGraphReuseTelemetry

Returns the “default value” for a type.

impl Eq for ResidentGraphReuseTelemetry

impl PartialEq for ResidentGraphReuseTelemetry

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