What problem does it solve?

Go strings are immutable and allocations can blow up in hot paths; catgut.String provides a pool-backed mutable alternative with copy-detection safeguards.

Core Features & Use Cases

• Pooling via GetPool().GetWithRepool() to reuse buffers across operations.
• Mutable buffer-backed string with Reset() to avoid reallocations.
• Copy-detection to panic on accidental value copies in debug builds.
• Flexible I/O via Write, WriteTo, and ReadFrom for hot-path manipulation.
• Typical use on parsing identifiers, tags, and other performance-critical string handling.

Quick Start

Create a pooled catgut.String, set its value, and reuse it across iterations with Reset to minimize allocations.
