Enum FillStrategy 

pub enum FillStrategy {
    ForwardFill,
    BackwardFill,
    LinearInterpolate,
    Zero,
    Skip,
}

Strategy for filling missing time-series points

Variants

ForwardFill

Carry forward the last observed value

BackwardFill

Use the next observed value (requires future data)

LinearInterpolate

Linear interpolation between surrounding points

Zero

Fill with zero/default value

Skip

Skip missing points (no output for missing intervals)

Implementations

impl FillStrategy

pub fn fill( &self, prev_value: Option<f64>, next_value: Option<f64>, prev_time: Option<DateTime<Utc>>, next_time: Option<DateTime<Utc>>, target_time: DateTime<Utc>, ) -> NormalizationResult<Option<f64>>

Fill a missing value given surrounding context

Arguments

• prev_value - The last observed value before the gap
• next_value - The next observed value after the gap
• prev_time - Timestamp of previous value
• next_time - Timestamp of next value
• target_time - Timestamp to fill

Returns

Some(value) if a value should be filled, None if point should be skipped

pub fn requires_future_data(&self) -> bool

Check if this strategy requires future data
