Struct PdhSnapshot 

pub struct PdhSnapshot {
    pub at_ms: u64,
    pub engine_util: Vec<(ParsedInstance, f64)>,
    pub proc_dedicated: Vec<(ParsedInstance, f64)>,
    pub proc_shared: Vec<(ParsedInstance, f64)>,
    pub adapter_dedicated: Vec<(ParsedInstance, f64)>,
    pub adapter_shared: Vec<(ParsedInstance, f64)>,
}

One formatted collection of every GPU counter stream — pure data, so the aggregation functions above are testable from scripted values on any OS. Built on Windows by [SharedPdh::snapshot]; both Windows backends read the same snapshot.

Empty vectors are the normal GPU-less/first-sample state, not an error.

Fields

at_ms: u64

When this collection happened (unix millis) — one timestamp per frame.

engine_util: Vec<(ParsedInstance, f64)>

\GPU Engine(*)\Utilization Percentage — busy % per (pid, engine) instance.

proc_dedicated: Vec<(ParsedInstance, f64)>

\GPU Process Memory(*)\Dedicated Usage — bytes per (pid, adapter).

proc_shared: Vec<(ParsedInstance, f64)>

\GPU Process Memory(*)\Shared Usage — bytes per (pid, adapter). Carried separately to the UI; never added into mem_bytes (dedicated vs shared is the honest split, §2.4).

adapter_dedicated: Vec<(ParsedInstance, f64)>

\GPU Adapter Memory(*)\Dedicated Usage — bytes per adapter (VidMm truth).

adapter_shared: Vec<(ParsedInstance, f64)>

\GPU Adapter Memory(*)\Shared Usage — bytes per adapter, shown separately.
