Trait LinkType 

pub trait LinkType:
    Number
    + Unsigned
    + Sized
    + TryFrom<u8>
    + FromPrimitive {
    // Required method
    fn funty(n: u8) -> Self;
}

Trait for unsigned integer types that can serve as node indices in trees and linked lists.

LinkType combines Number, Unsigned, TryFrom<u8>, and FromPrimitive and adds a convenience funty method for creating small constants.

Blanket implementation

Every type that satisfies the supertraits automatically implements LinkType, so standard unsigned types (u8, u16, u32, u64, usize) work out of the box:

use platform_trees::LinkType;

assert_eq!(u32::funty(0), 0u32);
assert_eq!(u64::funty(1), 1u64);
assert_eq!(usize::funty(42), 42usize);

Required Methods

fn funty(n: u8) -> Self

Convert a u8 value to Self.

This is a convenience method used internally for zero, one, and other small constants needed by tree and list algorithms.

Examples

use platform_trees::LinkType;

let zero = usize::funty(0);
let one  = u32::funty(1);
assert_eq!(zero, 0);
assert_eq!(one, 1);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
