Struct Decision 

pub struct Decision {
    pub decision_type: String,
    pub options: Vec<String>,
    pub chosen: String,
    pub rationale: IndexMap<String, f64>,
    pub rng_value: Option<f64>,
}

Algorithmic decision record.

Every decision MUST be logged with options considered, choice made, and the rationale (metrics that drove the choice).

Fields

decision_type: String

Decision type (e.g., rcl_selection, two_opt_apply, update_best)

options: Vec<String>

Options that were considered

chosen: String

The option that was chosen

rationale: IndexMap<String, f64>

Rationale: metrics that drove the choice

rng_value: Option<f64>

RNG value used (if decision involved randomness)

Implementations

impl Decision

pub fn new(decision_type: impl Into<String>, chosen: impl Into<String>) -> Self

Create a new decision record.

pub fn with_options(self, options: Vec<String>) -> Self

Add options that were considered.

pub fn with_rationale(self, name: impl Into<String>, value: f64) -> Self

Add a rationale metric.

pub fn with_rng_value(self, value: f64) -> Self

Set the RNG value used.

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<'de> Deserialize<'de> for Decision

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for Decision

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
