Address allocator trait.

Required Methods§

Source

fn allocate( &self, isd_as: IsdAsn, prefix: IpNet, claims: Token, ) -> Result<AddressAllocation, AddressAllocationError>

Allocate an address to a client.

  • The implementation SHOULD renew existing allocation, if the token claims matches an existing allocation and return the corresponding address.

  • The implementation MUST attempt to return a concrete address if either IPV4_WILDCARD or IPV6_WILDCARD is provided.

Source

fn put_on_hold(&self, id: AddressAllocationId) -> bool

Sets an address on hold

The hold prevents the address from being reallocated for a certain period of time.

Source

fn deallocate(&self, id: AddressAllocationId) -> bool

Immediately deallocates an address

Returns true if allocation was found and removed, false if allocation was not found
