Struct ArrowPreprocessResult

pub struct ArrowPreprocessResult {
    pub values: Float64Array,
    pub timestamps: Int64Array,
    pub gaps_filled: usize,
}

Expand description

Result of an Arrow-native preprocessing operation.

Fields§

§values: Float64Array

Processed values as Arrow Float64Array.

§timestamps: Int64Array

Aligned timestamps as Arrow Int64Array.

§gaps_filled: usize

Number of gaps filled during interpolation.
