Struct DecisionRandomEvidence 

pub struct DecisionRandomEvidence {
    pub draw_id: RandomDrawId,
    pub value: u64,
    pub upper_exclusive: u64,
    pub option_weights: Vec<DecisionOptionWeight>,
}

Fields

draw_id: RandomDrawId

value: u64

upper_exclusive: u64

option_weights: Vec<DecisionOptionWeight>

Implementations

impl DecisionRandomEvidence

pub fn selected_option( ticket: &DecisionTicket, option_weights: &[DecisionOptionWeight], value: u64, ) -> Result<String, DecisionError>

Selects the option of a random-policy draw. The weights must cover every available ticket option exactly once, in canonical order.

pub fn selected_candidate( ticket: &DecisionTicket, candidates: &[DecisionOptionWeight], value: u64, ) -> Result<String, DecisionError>

Selects the option of a random tie-break draw. The weights name only the near-equivalent candidates a policy left pending: at least two distinct available ticket options, each with a positive weight, in canonical order.

pub fn selected_option_from_weights( option_weights: &[DecisionOptionWeight], value: u64, upper_exclusive: u64, ) -> Result<String, DecisionError>
