Struct GeneratorOutput 

pub struct GeneratorOutput {
    pub row_map: Vec<u32>,
    pub columns: Vec<ArrayRef>,
}

Table-valued output of a LocyGenerator::generate call.

columns[c] holds the values of output variable c (for every emitted tuple), and row_map[i] is the index of the input row that produced emitted tuple i. All columns and row_map share the same length (the total number of emitted tuples), which may be more or fewer than the input row count.

Fields

row_map: Vec<u32>

For each emitted tuple, the input row index it was generated from.

columns: Vec<ArrayRef>

One array per output variable (in GenSignature::outputs order); each has length row_map.len().
