Crate blurhash_core 

blurhash-core

Fast BlurHash encoding and decoding in pure Rust.

BlurHash is a compact representation of a placeholder for an image. This crate provides high-performance encoding and decoding with precomputed lookup tables and cache-friendly memory access patterns.

Quick Start

use blurhash_core::{encode, decode};

// Encode: image pixels -> BlurHash string
let pixels = vec![128u8; 4 * 4 * 3]; // 4x4 gray image
let hash = encode(&pixels, 4, 4, 4, 3).unwrap();

// Decode: BlurHash string -> image pixels
let decoded = decode(&hash, 32, 32, 1.0).unwrap();
assert_eq!(decoded.len(), 32 * 32 * 3);
