Struct DeoptGuard 

pub struct DeoptGuard { /* private fields */ }

Tracks deopted kernels by their blueprint fingerprint.

Implementations

impl DeoptGuard

pub fn new() -> Self

Construct an empty guard with no Prometheus metrics wiring.

pub fn with_metrics(metrics: TensorWasmMetrics) -> Self

Construct an empty guard that also publishes success / fallback events to the supplied tensor_wasm_core::metrics::TensorWasmMetrics handle. The handle is Arc-backed and cheap to clone — pass the same handle used by the rest of the process so the tensor_wasm_offload_success_total and tensor_wasm_offload_fallback_total counters reflect the kernels driven by this guard.

pub fn is_deopted(&self, fingerprint: u64) -> bool

Returns true if the blueprint is currently deopted.

pub fn record_deopt(&self, fingerprint: u64, reason: DeoptReason)

Record a deopt event. Increments the fallback counter (and, if metrics are wired, the tensor_wasm_offload_fallback_total Prometheus counter).

pub fn record_success(&self)

Record a successful GPU execution. Increments the success counter (and, if metrics are wired, the tensor_wasm_offload_success_total Prometheus counter).

pub fn clear_deopt(&self, fingerprint: u64) -> Option<DeoptReason>

Reset deopt status for a fingerprint (e.g. after a kernel-cache invalidation that recompiles the PTX).

pub fn reason(&self, fingerprint: u64) -> Option<DeoptReason>

Reason for the most recent deopt of this kernel, if any.

pub fn success_total(&self) -> u64

Cumulative successful GPU executions.

pub fn fallback_total(&self) -> u64

Cumulative fallback events.

pub fn success_rate(&self) -> f64

Offload success rate as a fraction in [0, 1].

Trait Implementations

impl Default for DeoptGuard

fn default() -> Self

Returns the “default value” for a type.
