anybase 0.2.0

High-performance arbitrary base integer conversion library

This library provides efficient conversion between arbitrary base numeral systems using a custom character table approach. It supports very large numbers through its custom BigInt implementation that avoids overflow issues.

Features

• Convert between any two bases using custom character tables
• Supports arbitrarily large integers
• Optimized performance with limb-based arithmetic
• No external dependencies

Examples

use anybase::convert_base;

// Convert hexadecimal to octal
let result = convert_base("ff", "0123456789abcdef", "01234567").unwrap();
assert_eq!(result, "377");

// Convert decimal to hexadecimal
let result = convert_base("255", "0123456789", "0123456789abcdef").unwrap();
assert_eq!(result, "ff");

Performance

The library uses a limb-based BigInt implementation with a radix of 1,000,000,000 to efficiently handle large numbers while avoiding overflow. Arithmetic operations use u128 intermediates for additional safety. High-performance arbitrary base integer conversion (optimized version)

• Uses limb base = 1_000_000_000 (1e9)
• Uses u128 as intermediate to avoid overflow
