Struct LabeledVector 

pub struct LabeledVector {
    pub values: DVector<f64>,
    pub tickers: Vec<String>,
}

A length-N vector of floats paired with N ticker labels. Mirrors a pandas Series indexed by ticker name. Returned by every estimator that has a _labeled companion (e.g. crate::expected_returns::mean_historical_return_labeled) so callers can keep ticker order alongside the numerical values.

Fields

values: DVector<f64>

tickers: Vec<String>

Implementations

impl LabeledVector

pub fn new(values: DVector<f64>, tickers: Vec<String>) -> Result<Self>

pub fn get(&self, ticker: &str) -> Option<f64>

Look up a single value by ticker name.

pub fn to_map(&self) -> BTreeMap<String, f64>

Convert to a BTreeMap<String, f64> ordered alphabetically by ticker, matching PyPortfolioOpt’s OrderedDict style output.
