blosc-src

This is an FFI crate for using the Blosc compressor as implemented in c-blosc. The blosc compressor is a library of lossless compressors, which enables the developer to more easily use different compression algorithms depending on the data.

Non-rust dependencies

The crate builds c-blosc from source using the cc crate. As such it is required to have a C compiler installed.

Features

c-blosc can transparently use different compressors, but some of these are only available when included though cargo features. These include

• zlib
• zstd
• lz4

When these are requested they will be built from source and available for use by blosc.

Usage

As this crate only provides FFI, the examples from c-blosc also functions as examples for this crate. A simple roundtrip is included in test.rs.

The developer must take special care in dealing with memory and in multi-threaded environments. It is recommended to create and use a safe interface instead of this crate directly.
