Zstandard (Zstd) compression codec.

Zstd is a fast compression algorithm providing high compression ratios. It was developed by Yann Collet at Facebook and offers configurable compression levels from 1 (fastest) to 22 (smallest).

Options

• :level — Compression level, 1-22 (default: 3). Higher levels produce smaller output but take longer.
• :window_log — Window log size. Controls the maximum reference distance.

Performance Characteristics

• Fast decompression across all compression levels
• Compression speed configurable via level
• Excellent ratio at moderate speeds
• Supports dictionary compression for small data

Examples

iex> {:ok, compressed} = ExCodecs.encode(:zstd, "hello world")
iex> {:ok, decompressed} = ExCodecs.decode(:zstd, compressed)
iex> decompressed
"hello world"

iex> {:ok, compressed} = ExCodecs.encode(:zstd, "hello world", level: 9)
iex> is_binary(compressed)
true
