Prefix

typePrefix

An IP address prefix: the combination of an IP address and a prefix length.

A prefix can be constructed with the / operator or with the Prefix.new function. This operator takes an IpAddr and a u8 as operands.

Roto

let a = 1.1.1.0 / 8;
let b = 192.0.0.0 / 24;

functionaddr(self: Prefix) → IpAddr

Returns the IP address part of a prefix.

functioneq(self: Prefix, other: Prefix) → bool

Check whether those prefixes are the same.

functionlen(self: Prefix) → u8

Returns the length part of a prefix.

functionmax_addr(self: Prefix) → IpAddr

Returns the largest address of the prefix.

functionmin_addr(self: Prefix) → IpAddr

Returns the smallest address of the prefix.

This is the same as Prefix.addr.

functionnew(ip: IpAddr, len: u8) → Prefix

Construct a new prefix.

A prefix can also be constructed with the / operator.

Roto

let a = Prefix.new(192.169.0.0, 16);

// or equivalently
let b = 192.169.0.0 / 16;

functionto_string(self: Prefix) → String

Convert this value into a String.
