Struct AvroBinaryFormat 

pub struct AvroBinaryFormat {}

Raw Avro binary streaming format using Single-Object Encoding per record.

Each record written by the stream writer is framed with a prefix determined by the schema fingerprinting algorithm.

Trait Implementations

impl AvroFormat for AvroBinaryFormat

const NEEDS_PREFIX: bool = true

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<(), ArrowError>

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.
