Enum RowEncodingContext

Source

pub enum RowEncodingContext {
    Struct(Vec<Option<RowEncodingContext>>),
    Categorical(RowEncodingCategoricalContext),
    Decimal(usize),
}

Expand description

Additional context provided to row encoding regarding a column.

This allows communication based on the Polars datatype instead on the Arrow datatype. Since polars-row is used under polars-core, we don’t have access to the actual datatypes.
