pub struct TieredExecutionStats {
    pub tier: TieredExecutionTier,
    pub promotion: TieredPromotionStatus,
    pub interpreted_evaluations: u64,
    pub compiled_evaluations: u64,

Deterministic execution measurements for one tiered simulator.

This snapshot deliberately contains counts and lifecycle state rather than wall-clock samples. Applications can correlate it with structured celox.tiered.compile and celox.tiered.promote tracing spans, while performance tests should measure operations with a statistical benchmark harness such as Criterion. Reading a snapshot has no side effects and does not poll the compiler worker.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tier: TieredExecutionTier

Tier that will execute the next evaluation.

promotion: TieredPromotionStatus

Background compilation and promotion state.

interpreted_evaluations: u64

Evaluation iterations attempted by the interpreter.

compiled_evaluations: u64

Evaluation iterations attempted by generated code.

promoted_after_interpreted_evaluations: Option<u64>

Interpreter evaluation count at the point generated code was adopted.

safe_point_polls: u64

Number of scheduler safe-point polls performed while interpreted.

split_apply_deferrals: u64

Polls that could not promote because an evaluate/apply pair was open.

threshold_deferrals: u64

Polls that were held below the configured promotion threshold.
