Struct SelectThenActuate

Source

pub struct SelectThenActuate { /* private fields */ }

Expand description

Hard selection per seat followed by the shared ActuationPass lifecycle.

§Examples

use automation_structures::SelectThenActuate;

let mut pass = SelectThenActuate::new(1, 2)?;
pass.update_score(0, 1, 9)?;
assert_eq!(pass.evaluate(0)?, 1);
pass.actuate(0)?;
pass.finish()?;
assert!(pass.is_complete());

Implementations§

Source §

impl SelectThenActuate

Source

pub fn new( num_seats: usize, num_candidates: usize, ) -> Result<Self, SelectThenActuateBuildError>
