pub struct JsonSerializer {}Expand description
Define a struct for serializing Json records to a stream
Implementations§
Source§impl JsonSerializer
impl JsonSerializer
Sourcepub fn new() -> JsonSerializer
pub fn new() -> JsonSerializer
Constructor for the JsonSerializer object
Trait Implementations§
Source§impl BatchSerializer for JsonSerializer
impl BatchSerializer for JsonSerializer
Source§fn serialize(
&self,
batch: RecordBatch,
_initial: bool,
) -> Result<Bytes, DataFusionError>
fn serialize( &self, batch: RecordBatch, _initial: bool, ) -> Result<Bytes, DataFusionError>
Asynchronously serializes a
RecordBatch and returns the serialized bytes.
Parameter initial signals whether the given batch is the first batch.
This distinction is important for certain serializers (like CSV).Source§impl Default for JsonSerializer

fn type_name(&self) -> &'static str
Convenient wrapper for

Any::type_id is useless as a debugging aid (its Debug is just a mess of hex digits).Source§impl<T> BorrowMut<T> for Twhere
