Struct ArrowIpcCodec 

pub struct ArrowIpcCodec { /* private fields */ }

Available on crate feature arrow only.

A Decoder that yields one RecordBatch per IPC message.

The schema is read from the stream, so nothing needs to be configured to decode one.

Implementations

impl ArrowIpcCodec

pub fn new_with_max_length(max_length: usize) -> Self

A codec that rejects any single batch longer than max_length bytes.

Trait Implementations

impl Debug for ArrowIpcCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decoder for ArrowIpcCodec

type Item = Result<RecordBatch, StreamError>

Always Ok(_): the decoder carries dictionary state across the whole stream, so a message it could not read leaves it unable to interpret the ones after it.

type Error = StreamError

The type of unrecoverable frame decoding errors.

fn decode( &mut self, buf: &mut BytesMut, ) -> Result<Option<Self::Item>, StreamError>

Attempts to decode a frame from the provided buffer of bytes.

fn decode_eof( &mut self, buf: &mut BytesMut, ) -> Result<Option<Self::Item>, StreamError>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self>

where T: AsyncRead + AsyncWrite, Self: Sized,

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.
