[−][src]Struct parquet::decoding::DeltaBitPackDecoder
Delta binary packed decoder.
Supports INT32 and INT64 types.
See DeltaBitPackEncoder for more information.
Methods
impl<T: DataType> DeltaBitPackDecoder<T>[src]
impl<T: DataType> DeltaBitPackDecoder<T>pub fn new() -> Self[src]
pub fn new() -> SelfCreates new delta bit packed decoder.
pub fn get_offset(&self) -> usize[src]
pub fn get_offset(&self) -> usizeReturns underlying bit reader offset.

impl<T: DataType> Decoder<T> for DeltaBitPackDecoder<T>fn set_data(&mut self, data: ByteBufferPtr, _: usize) -> Result<()>[src]
fn set_data(&mut self, data: ByteBufferPtr, _: usize) -> Result<()>Sets the data to decode to be data, which should contain num_values of values to decode. Read more
fn get(&mut self, buffer: &mut [T::T]) -> Result<usize>[src]
fn get(&mut self, buffer: &mut [T::T]) -> Result<usize>Consumes values from this decoder and write the results to buffer. This will try to fill up buffer. Read more
fn values_left(&self) -> usize[src]
fn values_left(&self) -> usizeReturns the number of values left in this decoder stream.
fn encoding(&self) -> Encoding[src]
fn encoding(&self) -> EncodingReturns the encoding for this decoder.

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
