Enum Encoder

pub(crate) enum Encoder<'a> {
    Stateless,
    Dictionary(Rows, Row<'a>),
    Struct(Rows, Row<'a>),
    List(Rows),
    RunEndEncoded(Rows),
}

Variants

Stateless

No additional encoder state is necessary

Dictionary(Rows, Row<'a>)

The encoding of the child array and the encoding of a null row

Struct(Rows, Row<'a>)

The row encoding of the child arrays and the encoding of a null row

It is necessary to encode to a temporary Rows to avoid serializing values that are masked by a null in the parent StructArray, otherwise this would establish an ordering between semantically null values

List(Rows)

The row encoding of the child array

RunEndEncoded(Rows)

The row encoding of the values array
