Trait BuildersLike 

pub trait BuildersLike {
    type Row;
    type Error: Error;

    // Required methods
    fn append_row(&mut self, row: Self::Row) -> Result<(), Self::Error>;
    fn append_option_row(
        &mut self,
        row: Option<Self::Row>,

    // Provided method
    fn try_finish_into_batch(self) -> Result<RecordBatch, Self::Error>
       where Self: Sized { ... }
}

Unified interface for building batches across typed and dynamic schemas.

Required Associated Types

type Row

The row representation accepted by these builders.

type Error: Error

The error type returned by these builders.

Required Methods

fn append_row(&mut self, row: Self::Row) -> Result<(), Self::Error>

Append a non-null row to all columns.

Errors

Returns an error if the dynamic path detects an append/type/builder issue.

fn append_option_row( &mut self, row: Option<Self::Row>, ) -> Result<(), Self::Error>

Append an optional row; None appends a null to all columns.

Errors

Returns an error if the dynamic path detects an append/type/builder issue.

fn finish_into_batch(self) -> RecordBatch

Finish building and convert accumulated arrays into a RecordBatch.

Provided Methods

fn try_finish_into_batch(self) -> Result<RecordBatch, Self::Error>

where Self: Sized,

Try to finish building a RecordBatch, returning an error with richer diagnostics when available (e.g., dynamic nullability).

Errors

Returns an error when batch assembly fails (e.g., dynamic nullability).
