Crate trueno_zram_core 

SIMD-accelerated memory compression for Linux zram.

This crate provides high-performance LZ4 and Zstandard compression optimized for 4KB memory pages, with runtime SIMD dispatch.

Example

use trueno_zram_core::{CompressorBuilder, Algorithm, PageCompressor, PAGE_SIZE};

let compressor = CompressorBuilder::new()
    .algorithm(Algorithm::Lz4)
    .build()
    .unwrap();

let page = [0u8; PAGE_SIZE];
let compressed = compressor.compress(&page).unwrap();
let decompressed = compressor.decompress(&compressed).unwrap();

assert_eq!(page, decompressed);
