Trait RecordBatchWriter 

pub trait RecordBatchWriter {
    // Required methods
    fn write(&mut self, batch: &RecordBatch) -> Result<(), ArrowError>;
    fn close(self) -> Result<(), ArrowError>;
}

Trait for types that can write RecordBatch’s.

Required Methods

fn write(&mut self, batch: &RecordBatch) -> Result<(), ArrowError>

Write a single batch to the writer.

fn close(self) -> Result<(), ArrowError>

Write footer or termination data, then mark the writer as done.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
