SPDP Rust Bindings
See the Texas State page for information about this lossless codec for numerical data. Note that I am not the original author; this just binds to the original (v1.1) C source code.
Usage and Safety
READ THIS IF YOU WANT TO USE THE BINDINGS!
Unstated by the original authors, but to avoid segfaults and memory corrupts during batches, note:
- Input buffers get modified, as well as output buffers.
- During compression, the output buffer must be at least
2 * n + 9
bytes long, wheren
is the length of the input buffer. - During decompression, the input(!) buffer must be at least as long as the
output buffer.
To actually use this, you'll want to store both compressed and uncompressed
sizes somewhere else, then populate an input buffer of length
max(input_size, output_size)
and an output buffer of lengthoutput_size
.
Also Relevant
- Pcodec: another lossless codec for numerical data; contains a CLI with with benchmarks that compare vs. SPDP and others.
