Types ¶
type CombinedAllocator ¶
type CombinedAllocator = gonnectsubnet.CombinedAllocator
CombinedAllocator allocates both subnets and IP addresses.
func NewDefaultAllocator ¶
func NewDefaultAllocator(config DefaultAllocatorConfig) *CombinedAllocator
NewDefaultAllocator creates a gonnect default allocator that avoids address space currently used by local network interfaces.
The returned allocator wraps config.IPFilter and config.SubnetFilter. A nil caller filter is treated as allowing all candidates that pass the system checks.
IP candidates are rejected when the same address is assigned to any local network interface.
Subnet candidates are rejected when they exactly match a local interface network, when they contain any local interface address, or when they overlap a local interface network. Only the overlap check ignores local interface networks broader than /8, because networks such as 0.0.0.0/0 and ::/0 are too broad to be useful blockers and would collide with almost every allocation.
The local interface state is checked for each candidate allocation try. If interface enumeration fails, the allocator falls back to the caller-provided filters only for that candidate.
type DefaultAllocatorConfig ¶
type DefaultAllocatorConfig = gonnectsubnet.DefaultAllocatorConfig
DefaultAllocatorConfig configures NewDefaultAllocator.
type IPFilter ¶
type IPFilter = gonnectsubnet.IPFilter
IPFilter decides whether an IP address may be allocated.
type SubnetFilter ¶
type SubnetFilter = gonnectsubnet.SubnetFilter
SubnetFilter decides whether a subnet may be allocated.
