Struct AvroBinaryFormat 

pub struct AvroBinaryFormat;

Unframed Avro binary streaming format (“raw Avro record body bytes (no prefix, no OCF header)”).

Each record written by the stream writer contains only the raw Avro record body bytes (i.e., the Avro binary encoding of the datum) with no per-record prefix and no Object Container File (OCF) header.

This format is useful when another transport provides framing (for example, length-delimited buffers) or when embedding Avro record payloads inside a larger envelope.

Trait Implementations

impl AvroFormat for AvroBinaryFormat

const NEEDS_PREFIX: bool = false

If true, the writer for this format will query single_object_prefix() and write the prefix before each record. If false, the writer can skip this step. This is a performance hint for the writer.

fn start_stream<W: Write>( &mut self, _writer: &mut W, _schema: &Schema, compression: Option<CompressionCodec>, ) -> Result<(), AvroError>

Write any bytes required at the very beginning of the output stream (file header, etc.). Implementations must not write any record data.

fn sync_marker(&self) -> Option<&[u8; 16]>

Return the 16‑byte sync marker (OCF) or None (binary stream).

impl Debug for AvroBinaryFormat

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

Formats the value using the given formatter.

impl Default for AvroBinaryFormat

fn default() -> AvroBinaryFormat

Returns the “default value” for a type.
