Struct Sysfs 

pub struct Sysfs { /* private fields */ }

Reader for a (possibly simulated) /sys + /proc pair.

Implementations

impl Sysfs

pub fn system() -> Self

The real filesystem.

pub fn with_roots( sys_root: impl Into<PathBuf>, proc_root: impl Into<PathBuf>, ) -> Self

A simulated tree, used by tests and by --sysroot for debugging a captured topology from another machine.

pub fn read_topology( &self, process_affinity: Option<CpuSet>, ) -> Result<Topology>

Build the complete Topology.

process_affinity is passed in rather than read here because it comes from a syscall, not a file. When None, the online set is assumed, which is what a fresh process without an inherited mask sees.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sysfs

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

Formats the value using the given formatter.

impl Default for Sysfs

fn default() -> Self

Returns the “default value” for a type.
