BatchStreamDecoder

laminar_core::serialization

Struct BatchStreamDecoder 

Source 
pub struct BatchStreamDecoder { /* private fields */ }
Expand description

Decoder for a stream produced by BatchStreamEncoder: feed each chunk in order; the first chunk’s schema decodes all later schema-less chunks.

Implementations§

Source§

impl BatchStreamDecoder

Source

pub fn new() -> Self

Creates an empty decoder that has not yet seen a schema.

Source

pub fn decode_chunk( &mut self, bytes: Vec<u8>, ) -> Result<Vec<RecordBatch>, ArrowError>

Decode every complete batch in one chunk; a batch straddling a chunk boundary is buffered until the rest arrives, preserving order.

§Errors

[ArrowError] if the bytes aren’t a valid continuation (e.g. a batch before any schema).
