Strix - A High-Performance String Utility Package

Strix is a Go package that provides high-performance string manipulation functions. It offers optimized versions of common string operations, such as HasPrefix, HasSuffix, Index, Contains, Repeat, and more.

This repository includes a comparison of benchmark results between the Strix functions and the standard library strings functions. The goal is to provide efficient alternatives for string manipulation with minimal memory allocation and faster execution.

Features

• Optimized versions of common string manipulation functions.
• Memory-efficient implementations with reduced allocations.
• Easy-to-use API with support for most common string operations.

Benchmark Results

The following are the results of benchmarking the Strix package functions against the corresponding strings functions in the Go standard library. These benchmarks were run on an Apple M1 Pro with the darwin operating system and arm64 architecture.

Observations

• Strix functions perform similarly or better in terms of execution time compared to the strings package in most cases.
• Memory Allocations: Strix's functions often have reduced memory allocations, especially in cases like Clone, Contains, Count, and Split, where the Strix functions either use less memory or do not allocate additional memory compared to the strings package.
• Performance: Strix's performance for string manipulation operations such as HasPrefix, Contains, and IndexByte is on par or faster than the strings functions in most cases, particularly in the case of smaller strings.

Additional Functions

In addition to the common string manipulation functions, Strix also provides various validation functions such as IsNumeric, IsAlpha, IsEmail, IsURL, IsIPv4, IsHexColor, IsPalindrome and many more. These functions help in validating different types of strings efficiently.

Installation

You can install the Strix package using the following Go command:
