Interface RandomNumberGenerator

Interface for random number generators. This is the TypeScript equivalent of Rust's RandomNumberGenerator trait which extends RngCore + CryptoRng.

This is compatible with the RandomNumberGenerator Swift protocol used in MacOS and iOS, which is important for cross-platform testing.

interface RandomNumberGenerator {
    nextU32(): number;
    nextU64(): bigint;
    fillBytes(dest: Uint8Array): void;
    randomData(size: number): Uint8Array;
    fillRandomData(data: Uint8Array): void;
}
