Struct ProcfsSensor 

pub struct ProcfsSensor { /* private fields */ }

Sensor that reads a value from a /proc filesystem file by parsing a key-value format.

Common uses:

• /proc/loadavg — CPU load average (first field)
• /proc/meminfo — MemAvailable: / MemTotal: for memory pressure
• /proc/stat — CPU time slices

Implementations

impl ProcfsSensor

pub fn new( id: impl Into<String>, kind: SensorKind, path: impl Into<String>, parser: SensorParser, ) -> Self

Create a new procfs sensor with a custom parser.

pub fn loadavg() -> Self

Create a CPU load average sensor from /proc/loadavg.

pub fn mem_pressure() -> Self

Create a memory pressure sensor from /proc/meminfo.

Returns 1.0 - (MemAvailable / MemTotal), clamped to [0, 1].

Trait Implementations

impl Debug for ProcfsSensor

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

Formats the value using the given formatter.

impl SensorDevice for ProcfsSensor

fn id(&self) -> &str

Unique sensor identifier.

fn kind(&self) -> SensorKind

Sensor type.

fn read(&self) -> Option<SensorReading>

Read current value. Returns None if the sensor is unavailable.

fn is_available(&self) -> bool

Whether the sensor is currently available/connected.
