Module verified::uint

Type-level unsigned integers.

Type operators implemented:

From core::ops: BitAnd, BitOr, BitXor, Shl, Shr, Add, Sub, Mul, Div, and Rem. From typenum: Same, Cmp, and Pow.

Rather than directly using the structs defined in this module, it is recommended that you import and use the relevant aliases from the consts module.

Example

use std::ops::{BitAnd, BitOr, BitXor, Shl, Shr, Add, Sub, Mul, Div, Rem};
use typenum::{Unsigned, U1, U2, U3, U4};

assert_eq!(<U3 as BitAnd<U2>>::Output::to_u32(), 2);
assert_eq!(<U3 as BitOr<U4>>::Output::to_u32(), 7);
assert_eq!(<U3 as BitXor<U2>>::Output::to_u32(), 1);
assert_eq!(<U3 as Shl<U1>>::Output::to_u32(), 6);
assert_eq!(<U3 as Shr<U1>>::Output::to_u32(), 1);
assert_eq!(<U3 as Add<U2>>::Output::to_u32(), 5);
assert_eq!(<U3 as Sub<U2>>::Output::to_u32(), 1);
assert_eq!(<U3 as Mul<U2>>::Output::to_u32(), 6);
assert_eq!(<U3 as Div<U2>>::Output::to_u32(), 1);
assert_eq!(<U3 as Rem<U2>>::Output::to_u32(), 1);

Structs

UInt	UInt is defined recursively, where B is the least significant bit and U is the rest of the number. Conceptually, U should be bound by the trait Unsigned and B should be bound by the trait Bit, but enforcing these bounds causes linear instead of logrithmic scaling in some places, so they are left off for now. They may be enforced in future.
UTerm	The terminating type for UInt; it always comes after the most significant bit. UTerm by itself represents zero, which is aliased to U0.

Traits

GetBit
PowerOfTwo	The marker trait for type-level numbers which are a power of two.
SetBit	A type operator that, when implemented for unsigned integer N, sets the bit at position I to B.
Unsigned	The marker trait for compile time unsigned integers.

Type Definitions

GetBitOut
SetBitOut	Alias for the result of calling SetBit: SetBitOut<N, I, B> = <N as SetBit<I, B>>::Output.
