}

Runtime observability snapshot for a crate::WgpuBackend.

Feed into metrics pipelines (prometheus, OpenTelemetry, Datadog) for dashboards and alerting. Reads are lock-free; safe to call from a hot scrape loop.

Fields

adapter_name: Arc<str>

Adapter name the backend is bound to (e.g. "NVIDIA GeForce RTX 5090").

pipeline_cache_entries: usize

Live entries in the pipeline cache.

pipeline_cache_capacity: usize

Soft cap before eviction triggers.

pipeline_cache_bytes: usize

Estimated bytes retained by the pipeline cache.

pipeline_cache_byte_capacity: usize

Estimated byte cap before eviction triggers.

pipeline_cache_hits: u64

Pipeline-cache lookup hits since backend construction.

pipeline_cache_misses: u64

Pipeline-cache lookup misses since backend construction.

pipeline_cache_insertions: u64

Pipeline-cache insertions since backend construction.

pipeline_cache_evictions: u64

Capacity-driven pipeline-cache evictions since backend construction.

pipeline_cache_hit_rate: f64

Hit ratio over all pipeline-cache lookups.

persistent_pool: BufferPoolStats

Persistent buffer pool counters (allocations, hits, releases, evictions).
