pub trait Factor: Send + Sync {
// Required methods
fn name(&self) -> &str;
fn score(&self, item: &dyn Scoreable, state: &ProfileState, now: u64) -> f32;
}Expand description
Core trait every scoring factor must implement.
Callers define domain logic entirely through factors. Built-in factors (Challenge, Spacing, Coverage) are provided as reference implementations — callers may use, replace, or extend them.
A factor returns a score in [0.0, 1.0]. Engine multiplies all factor scores together — multiplicative pipeline. A near-zero score from any single factor suppresses the item entirely.
Required Methods§
fn name(&self) -> &str
fn score(&self, item: &dyn Scoreable, state: &ProfileState, now: u64) -> f32
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
