Struct Signal 

pub struct Signal {
    pub id: &'static str,
    pub audience: Audience,
    pub base: f64,
    pub metric: fn(&EngineInputs) -> f64,
}

A registered nudge. metric extracts the raw pressure numerator m from the inputs; base is the denominator b; the signal fires when (m / b) * factor >= 1.

Fields

id: &'static str

Stable identifier (also the throttle-map key).

audience: Audience

Who the nudge is for.

base: f64

The pressure denominator b (> 0).

metric: fn(&EngineInputs) -> f64

Extract the raw pressure numerator m from the inputs.

Implementations

impl Signal

pub fn pressure(&self, inputs: &EngineInputs) -> f64

Normalized pressure m / b (independent of aggressiveness).
