Enum Decision 

pub enum Decision {
    NeedMoreData {
        sessions_each: usize,
        required: usize,
    },
    Hold {
        posterior: f64,
    },
    Promote {
        posterior: f64,
    },
}

Outcome of a promotion evaluation.

Variants

NeedMoreData

At least one arm has too few sessions to decide yet.

Fields

sessions_each: usize

Sessions in the thinner arm.

required: usize

Minimum required per arm.

Hold

Enough data, but posterior below threshold. Keep running.

Fields

posterior: f64

Current estimated P(challenger > champion).

Promote

Promote: posterior crossed threshold.

Fields

posterior: f64

Current estimated P(challenger > champion).

Trait Implementations

impl Clone for Decision

fn clone(&self) -> Decision

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Decision

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Decision

fn eq(&self, other: &Decision) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Decision

impl StructuralPartialEq for Decision
