strutil

StrUtil Package (internal/strutil)

High-performance string utilities.

Overview

This package provides optimized string manipulation functions used throughout HotPlex, particularly in security-critical paths like regex scanning.

Usage

import "github.com/hrygo/hotplex/internal/strutil"

// Truncate string with ellipsis
short := strutil.Truncate("very long string...", 10)
// Result: "very lo..."

// Safe substring (handles Unicode)
sub := strutil.SafeSubstring("Hello 世界", 0, 8)

Design Goals

• Zero Allocation: Critical paths minimize garbage collection
• Unicode Safe: Proper handling of multi-byte characters
• Security Focused: Used in WAF pattern matching
