Expand description

This trait defines how to format a sequence of JSON objects to a byte stream.

Provided Methods§

source

fn start_stream<W: Write>(&self, _writer: &mut W) -> Result<(), ArrowError>

write any bytes needed at the start of the file to the writer

source

fn start_row<W: Write>( &self, _writer: &mut W, _is_first_row: bool, ) -> Result<(), ArrowError>

write any bytes needed for the start of each row

source

fn end_row<W: Write>(&self, _writer: &mut W) -> Result<(), ArrowError>

write any bytes needed for the end of each row

source

fn end_stream<W: Write>(&self, _writer: &mut W) -> Result<(), ArrowError>

write any bytes needed for the start of each row

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.
