PagerStats

Struct PagerStats 

Source
pub struct PagerStats {
    pub faults: AtomicU64,
    pub prewarmed: AtomicU64,
    pub port_reinstalls: AtomicU64,
    pub forwarded_exceptions: AtomicU64,
}
Expand description

Pager statistics — exposed for tracing and unit tests. All counters are monotonic so a test can assert “fault count went up by N”.

Fields§

§faults: AtomicU64

Number of fault requests served.

§prewarmed: AtomicU64

Number of pages pre-warmed at registration.

§port_reinstalls: AtomicU64

Number of times the pager re-installed its exception port after detecting LLDB drift.

§forwarded_exceptions: AtomicU64

Number of exceptions forwarded to a prior handler (out-of-region faults).

Implementations§
