Crate ferromark 

ferromark: Ultra-high-performance Markdown to HTML compiler

This crate provides a streaming Markdown parser optimized for speed, targeting 20-30% better throughput than existing Rust parsers.

Design Principles

• No AST: streaming events only
• No regex: pure byte-level scanning
• No backtracking: O(n) time on all inputs
• Minimal allocations: ranges into input buffer

Future Optimizations

• simdutf / simdutf8: SIMD-accelerated UTF-8 validation for input
• NEON intrinsics for ARM: inline marker scanning
• Loop unrolling in hot paths (4x unroll like md4c)
