Trait Sensor 

Source 
pub trait Sensor: Send {
    // Required methods
    fn descriptor(&self) -> SensorDescriptor;
    fn bind(&mut self, ctx: &mut BindContext<'_>) -> Result<()>;
    fn observe(&mut self, out: &mut StateWriter<'_>) -> SensorOutcome;
}
Expand description

A passive source of observations.

Implementors must be honest about Perturbation. The reflector checks that no registered sensor declares Perturbation::Material, but it cannot check that a sensor declaring Negligible is telling the truth. That is a review obligation, and it is why each sensor’s module documentation states the physical basis for its claim.

Required Methods§

Source

fn descriptor(&self) -> SensorDescriptor

Source

fn bind(&mut self, ctx: &mut BindContext<'_>) -> Result<()>

Resolve everything resolvable once: which entities exist, which files to read, which descriptors to open, which columns to fill.

This is where CoreScout earns its keep as a normalisation layer. Path construction, parsing setup and capability probing happen here, once per epoch, so that Sensor::observe is close to pure I/O.

Returning Err means the sensor is unavailable on this machine, which is a normal outcome. The error’s kind decides what the mirror reports: permission denied, unsupported, or merely unavailable.

Source

fn observe(&mut self, out: &mut StateWriter<'_>) -> SensorOutcome

Sample the machine once.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
