Required Associated Constants

const COLUMNS: usize

Required Associated Types

type Builder: RowBatchBuilder<Self>

type View: RowFormatView<Self>

Required Methods

fn builder(fields: &[Arc<Field>]) -> Result<Self::Builder>

fn view( rows: usize, fields: &[Arc<Field>], arrays: &[ArrayRef], ) -> Result<Self::View>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
