BigInt

this this(T n): Create BigInt from any integer
this this(string str): Create BigInt from a string. If the string starts with 0x the rest of the string will be interpreted as hexadecimal digits. Otherwise, it will be interpreted as a decimal number.
this this(const(ubyte)* input, size_t length, Base base): Create a BigInt from an integer in a ubyte array
this this(RandomNumberGenerator rng, size_t bits, bool set_high_bit): Create a random BigInt of the specified size
this this(Sign s, size_t size): Create BigInt of specified size, all zeros
this this(BigInt other): Move constructor
