Struct PidKoidSession 

pub struct PidKoidSession { /* private fields */ }

A reader’s session and query interface for pid/koid mappings. Recording in the kernel stays active while at least one session is held across any client; dropping the session ends this client’s interest. When all active sessions have been dropped, the shared map is released and recording ceases.

Resolution queries are only reachable through a session, which enforces at compile time that lookups happen while recording is active.

Implementations

impl PidKoidSession

pub fn resolve_tid_to_koid(&self, tid: tid_t) -> Option<Koid>

Forward resolution: maps a Linux tid to its thread koid, returning None on a miss.

pub fn resolve_pid_to_koid(&self, pid: pid_t) -> Option<Koid>

Forward resolution: maps a Linux pid to its process koid, returning None on a miss.

pub fn resolve_koids(&self, pkoid: Koid, tkoid: Koid) -> Option<LinuxIdentity>

Reverse resolution: maps sampled (process koid, thread koid) to Linux identity, with negative caching for native Fuchsia processes. See TracePerformanceEventManager::resolve_koids.

Trait Implementations

impl Drop for PidKoidSession

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
