Struct Tagged 

Source
pub struct Tagged<const N: u64, T>(/* private fields */);
Expand description

Statically tag a value.

§Example

use minicbor::data::{IanaTag, Tagged};

let input = [
    0xc0, 0x74, 0x32, 0x30, 0x31, 0x33, 0x2d, 0x30,
    0x33, 0x2d, 0x32, 0x31, 0x54, 0x32, 0x30, 0x3a,
    0x30, 0x34, 0x3a, 0x30, 0x30, 0x5a
];

let date_time: Tagged<0, &str> = minicbor::decode(&input)?;
assert_eq!(date_time.tag(), IanaTag::DateTime.tag());
assert_eq!(date_time.value(), &"2013-03-21T20:04:00Z");
