Crate rustyhdf5_filters 

Filter and compression pipeline for HDF5.

Provides deflate (zlib) decompression/compression with multiple backend options:

• Default: miniz_oxide (pure Rust, no C dependencies)
• fast-deflate feature: zlib-ng via flate2 (~2-3x faster, matches C HDF5)
• apple-compression feature: Apple Compression Framework on macOS (hardware-accelerated on Apple Silicon)

Backend priority: apple-compression > zlib-ng > miniz_oxide.

Modules

fast_deflate

Fast deflate backends: Apple Compression Framework and zlib-ng.

Functions

deflate_backend

Returns the name of the currently active deflate backend.

deflate_compress

Compress data with zlib.

deflate_compress_miniz

Compress data using the pure-Rust miniz_oxide backend. Always available regardless of feature flags, for comparison/testing.

deflate_decompress

Decompress zlib-compressed data.

deflate_decompress_miniz

Decompress zlib data using the pure-Rust miniz_oxide backend. Always available regardless of feature flags, for comparison/testing.
