Struct LinuxPlatform 

pub struct LinuxPlatform { /* private fields */ }

The Linux implementation of Platform.

Implementations

impl LinuxPlatform

pub fn new() -> Self

pub fn with_sysfs(sysfs: Sysfs) -> Self

Read topology from an alternate filesystem root. Used by tests and by the hidden --sysroot flag for inspecting a captured tree.

Trait Implementations

impl Default for LinuxPlatform

fn default() -> Self

Returns the “default value” for a type.

impl Platform for LinuxPlatform

fn name(&self) -> &'static str

Human-readable backend name, e.g. "linux".

fn discover_topology(&self) -> Result<Topology>

Discover the full machine topology.

fn pin_current_thread(&self, cpu: LogicalId) -> Result<()>

Restrict the calling thread to a single logical CPU.

fn set_current_thread_affinity(&self, cpus: &CpuSet) -> Result<()>

Set the calling thread’s affinity to an arbitrary set.

fn current_thread_affinity(&self) -> Result<CpuSet>

Read the calling thread’s current affinity mask.

fn process_affinity(&self) -> Result<CpuSet>

Read the affinity mask of the whole process.

fn thread_switch_counters(&self) -> Option<SwitchCounters>

Sample the calling thread’s context-switch counters, when the platform can report them per-thread. None means “no interference data”, and callers degrade to statistical outlier detection alone.

fn spawn_with_affinity( &self, command: &mut Command, cpus: &CpuSet, ) -> Result<Child>

Spawn a child process confined to cpus.

fn thread_cycles(&self) -> Option<u64>

Cycles the calling thread has actually been executing.
