Struct Tagged

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

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");

impl<const N: u64, T: Ord> Ord for Tagged<N, T>

fn cmp(&self, other: &Tagged<N, T>) -> Ordering

This method returns an Ordering between self and other.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
