Struct PagerStats 

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

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

impl PagerStats

pub fn snapshot(&self) -> PagerStatsSnapshot

Snapshot the counters into a plain-data struct for tests / logging.

Trait Implementations

impl Debug for PagerStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PagerStats

fn default() -> PagerStats

Returns the “default value” for a type.
