Crate async_regex 

async-regex

Empower regex with streaming capabilities!

This crate provides high-performance streaming pattern search that leverages the power of regex for pattern matching while adding streaming capabilities for processing large data streams without loading everything into memory.

Key Features

• Regex-powered pattern matching: Uses the robust regex crate for pattern matching
• Streaming support: Process data as it arrives without loading everything into memory
• Async and sync APIs: Both async and synchronous versions available
• Multi-byte pattern support: Unlike standard read_until which only supports single bytes
• Memory efficient: Minimal memory footprint with zero-copy operations where possible

Why This Crate?

The standard std::io::BufRead::read_until and tokio::io::AsyncBufRead::read_until methods only support single-byte delimiters. This crate extends that functionality to support multi-byte patterns using regex, making it perfect for parsing protocols, log files, and other structured data streams.

Constants

CRLF

Carriage Return + Line Feed constant for convenience
