Function reverse_string 

pub fn reverse_string(input: &str) -> String

Reverses the input string.

Reverses the order of all characters in the string. This is a simple transformation that can be used for basic obfuscation or testing palindrome detection. Works correctly with Unicode characters.

Use Cases

• Basic Obfuscation: Simple reversible transformation
• Testing: Verify string reversal implementations
• Palindromes: Test palindrome detection logic
• Data Encoding: Combine with other transformations for layered encoding

Examples

use redstr::reverse_string;

assert_eq!(reverse_string("hello"), "olleh");
assert_eq!(reverse_string("test123"), "321tset");

// Reversing twice returns the original
let text = "example";
assert_eq!(reverse_string(&reverse_string(text)), text);

// Works with Unicode
assert_eq!(reverse_string("café"), "éfac");
