Struct Selector 

pub struct Selector {
    pub exploration_rate: f32,
    /* private fields */
}

Selector — scores eligible items, applies exploration noise, returns best.

Fields

exploration_rate: f32

Fraction of noise added to score. 0.0 = deterministic. Default 0.05.

Implementations

impl Selector

pub fn new(exploration_rate: f32) -> Self

pub fn select<'a>( &mut self, eligible: &[&'a Item], factors: &[Box<dyn Factor>], state: &ProfileState, now: u64, ) -> Result<&'a Item, AriaError>

Select best item from eligible list using factor pipeline scores. Returns reference to winning item.

pub fn seed(&mut self, seed: u64)

Re-seed the RNG — useful in tests for determinism.

Trait Implementations

impl Default for Selector

fn default() -> Self

Returns the “default value” for a type.
