Enum cbor_tools::Integer

pub enum Integer {
    U5(ZeroTo23),
    U8(u8),
    U16(u16),
    U32(u32),
    U64(u64),
    N5(ZeroTo23),

}

CBOR Integer type

use cbor_tools::{CborType, Integer, Encode};

let val = Integer::from(123);
// This is the CBOR encoding for an 8-bit integer.
assert_eq!(CborType::from(val).encode(), vec![0x18, 0x7B]);

CBOR integers will be represented in "canonical" form if the From<u8 | u32 | u64> impls are used. Non-canonical forms can be created by initializing the struct directly:

let val = Integer::U32(100);
assert_eq!(CborType::from(val).encode(), vec![0x1a, 0, 0, 0, 0x64]);

Note: integers outside the range of [-2^64, 2^64-1] should be encoded as byte strings instead.
