eolify

High-performance line ending normalization for Rust.

eolify is a lightweight, allocation-conscious library for normalizing end-of-line (EOL) sequences in large text streams or buffers. It’s designed for high-throughput processing pipelines, data ingestion systems, and cross-platform tooling where consistency and efficiency matter.

Features

• Fast and memory-efficient — optimized for bulk text processing
• Normalizes EOLs to a consistent format (\r\n for now)
• Minimal dependencies — ideal for embedding in performance-critical code
• Handles mixed endings (\n, \r\n, \r) gracefully
• Built with large-scale text data and streaming I/O in mind

Current status

Currently supports: normalization to CRLF (\r\n) using a chunk based API or through a Read implementation.

Planned:

• LF (\n) normalization
• Write
• AsyncRead / AsyncWrite

Example

use eolify::crlf;

let text = "one\nline\r\ntwo\rthree";
let normalized = crlf::normalize_str(text);
assert_eq!(normalized, "one\r\nline\r\ntwo\r\nthree");
