Trait cjdns_core::LabelBits

pub trait LabelBits: Sized + Copy + From<u32> + Shl<u32, Output = Self> + Shr<u32, Output = Self> + BitXor<Output = Self> + BitOr<Output = Self> + BitAnd<Output = Self> + Add<Output = Self> + Sub<Output = Self> + Eq + Display {
    const ZERO: Self;
    const ONE: Self;
    const BIT_SIZE: u32;
    const MAX_PAYLOAD_BITS: u32;

    fn highest_set_bit(&self) -> Option<u32>;
}

Describes types which can act as routing label's underlying data type.

Routing labels itself are opaque, so this trait is required for internal data manipulations.

The following parent traits of LabelBits are considered public: Sized, Copy, From<u32>, Eq, Display.

For label manipulation routines please see the cjdns-splice crate.

This trait is implemented for u64 and u128.

Associated Constants

const ZERO: Self

const ONE: Self

One (1) value for this data type.

const BIT_SIZE: u32

Bit size of the this data type.

const MAX_PAYLOAD_BITS: u32
