Struct RowProjectionOutput 

pub struct RowProjectionOutput {
    pub entity: String,
    pub columns: Vec<String>,
    pub rows: Vec<Vec<OutputValue>>,
    pub row_count: u32,
}

Row-oriented output from one accepted-schema-driven projection.

Fields

entity: String

Accepted entity name used for the read.

columns: Vec<String>

Selected output-column names in row order.

rows: Vec<Vec<OutputValue>>

Row-oriented output values.

row_count: u32

Number of returned rows.
