Struct IndicatorOutput 

pub struct IndicatorOutput { /* private fields */ }

Named column output, analogous to pd.DataFrame returned by Python calculate().

Keys are column names such as "SMA_20", "MACD_line", "ATR_14". Values are aligned Vec<f64> of the same length as the input slice. Leading warm-up entries are f64::NAN.

Implementations

impl IndicatorOutput

pub fn new() -> Self

Create an empty output.

pub fn insert(&mut self, name: impl Into<String>, values: Vec<f64>)

Insert a named column.

pub fn from_pairs<K: Into<String>>( pairs: impl IntoIterator<Item = (K, Vec<f64>)>, ) -> Self

Build from an iterator of (name, values) pairs.

pub fn get(&self, name: &str) -> Option<&[f64]>

Get the values for a named column.

pub fn latest(&self, name: &str) -> Option<f64>

Get the last (most recent) value of a named column, skipping NaN.

Mirrors Python’s indicator.get_value(-1).

pub fn columns(&self) -> impl Iterator<Item = &str>

All column names present in this output.

pub fn len(&self) -> usize

Number of rows (length of any column; all columns are guaranteed equal length).

pub fn is_empty(&self) -> bool

pub fn into_inner(self) -> HashMap<String, Vec<f64>>

Consume into the underlying map.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for IndicatorOutput

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

Formats the value using the given formatter.

impl Default for IndicatorOutput

fn default() -> IndicatorOutput

Returns the “default value” for a type.
