pub struct DeltaBitPackEncoder<T: DataType> { /* fields omitted */ }
Delta bit packed encoder.
Consists of a header followed by blocks of delta encoded values binary packed.
Delta-binary-packing:
[page-header] [block 1], [block 2], ... [block N]
Each page header consists of:
[block size] [number of miniblocks in a block] [total value count] [first value]
Each block consists of:
[min delta] [list of bitwidths of miniblocks] [miniblocks]
Current implementation writes values in put
method, multiple calls to put
to
existing block or start new block if block size is exceeded. Calling flush_buffer
writes out all data and resets internal state, including page header.
Supports only INT32 and INT64.
Creates new delta bit packed encoder.
Encodes data from values

Returns the encoding type of this encoder.
Returns an estimate of the encoded data, in bytes. Method call must be O(1). Read more
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

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
