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