Struct parquet::encoding::DeltaByteArrayEncoder [−][src]
pub struct DeltaByteArrayEncoder<T: DataType> { /* fields omitted */ }
Encoding for byte arrays, prefix lengths are encoded using DELTA_BINARY_PACKED encoding, followed by suffixes with DELTA_LENGTH_BYTE_ARRAY encoding.

impl<T: DataType> Encoder<T> for DeltaByteArrayEncoder<T>
fn put(&mut self, _values: &[T::T]) -> Result<()>
[src]
fn put(&mut self, _values: &[T::T]) -> Result<()>
Encodes data from values
.
fn encoding(&self) -> Encoding
[src]
fn encoding(&self) -> Encoding
Returns the encoding type of this encoder.
fn flush_buffer(&mut self) -> Result<ByteBufferPtr>
[src]
fn flush_buffer(&mut self) -> Result<ByteBufferPtr>
Flushes the underlying byte buffer that's being processed by this encoder, and return the immutable copy of it. This will also reset the internal state. Read more
