Struct AddressAllocator 

pub struct AddressAllocator { /* private fields */ }

An allocator of IP addresses.

Implementations

impl AddressAllocator

pub fn new( prefixes: Vec<IpNet>, rng: ChaCha8Rng, ) -> Result<Self, AllocatorCreationError>

Creates a new AddressAllocator.

Arguments

• prefixes - A list of non-overlapping prefixes to allocate from.
• rng - A random number generator for random address allocation.

pub fn free(&mut self, address: IpAddr) -> Result<(), AddressAllocatorError>

Frees a certain Address

Returns an error if the address is not in in Prefix

pub fn is_free(&self, address: IpAddr) -> bool

Check if an address is free

pub fn allocate( &mut self, requested: IpAddr, ) -> Result<IpAddr, AddressAllocatorError>

Allocate an address from the address allocator. If the requested address is unspecified, a random address of the given family is allocated.

Trait Implementations

impl Clone for AddressAllocator

fn clone(&self) -> AddressAllocator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AddressAllocator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AddressAllocator

fn eq(&self, other: &AddressAllocator) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
