Enum dataflow_types::ColumnSpec[][src]

pub enum ColumnSpec {
    Count(usize),
    Header {
        names: Vec<String>,
    },
}
Expand description

Determines the RelationDesc and decoding of CSV objects

Variants

Count(usize)

Tuple Fields

0: usize

The first row is not a header row, and all columns get default names like columnN.

Header

Fields

names: Vec<String>

The first row is a header row and therefore does become data

Each of the values in names becomes the default name of a column in the dataflow.

Implementations
