Struct parquet::encoding::RleValueEncoder [−][src]
pub struct RleValueEncoder<T: DataType> { /* fields omitted */ }
RLE/Bit-Packing hybrid encoding for values. Currently is used only for data pages v2 and supports boolean types.
Methods
impl<T: DataType> RleValueEncoder<T>[src]
impl<T: DataType> RleValueEncoder<T>Trait Implementations
impl<T: DataType> Encoder<T> for RleValueEncoder<T>[src]
impl<T: DataType> Encoder<T> for RleValueEncoder<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) -> EncodingReturns 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
