Struct PrefixPolicy 

pub struct PrefixPolicy { /* private fields */ }

The prefix lengths used to group addresses.

IPv6 hosts usually own a whole /64, so the default groups IPv6 at /64 and IPv4 at /32.

Examples

use net_io::PrefixPolicy;
assert_eq!(PrefixPolicy::DEFAULT.v6(), 64);
assert!(PrefixPolicy::new(33, 64).is_err());

Implementations

impl PrefixPolicy

pub const HOST: PrefixPolicy

Every address on its own: /32 and /128.

pub const DEFAULT: PrefixPolicy

/32 for IPv4 and /64 for IPv6.

pub const fn new(v4: u8, v6: u8) -> Result<PrefixPolicy, AddrError>

A policy with the given lengths.

Errors

AddrError::PrefixTooLong above 32 or 128.

let wide = net_io::PrefixPolicy::new(24, 48)?;
assert_eq!(wide.v4(), 24);

pub const fn v4(&self) -> u8

The IPv4 prefix length.

pub const fn v6(&self) -> u8

The IPv6 prefix length.
