Types ¶
type CIDRMap ¶
type CIDRMap struct {
Fd int
AddrSize int // max prefix length in bytes, 4 for IPv4, 16 for IPv6
Prefixlen uint32
// PrefixIsDynamic determines whether it's valid for entries to have
// a prefix length that is not equal to the Prefixlen above
PrefixIsDynamic bool
// contains filtered or unexported fields
}
CIDRMap refers to an LPM trie map at 'path'.
func OpenMap ¶
OpenMap opens a new CIDRMap. 'bool' returns 'true' if the map was created, and 'false' if the map already existed. prefixdyn denotes whether element's prefixlen can vary and we thus need to use a LPM trie instead of hash table.
func OpenMapElems ¶ added in v1.5.0
func OpenMapElems(path string, prefixlen int, prefixdyn bool, maxelem uint32) (*CIDRMap, bool, error)
OpenMapElems is the same as OpenMap only with defined maxelem as argument.
func (*CIDRMap) CIDRExists ¶
CIDRExists returns true if 'cidr' exists in map 'cm'
func (*CIDRMap) DeleteCIDR ¶ added in v1.5.0
DeleteCIDR deletes an entry from 'cm' with key 'cidr'.
func (*CIDRMap) InsertCIDR ¶ added in v1.5.0
InsertCIDR inserts an entry to 'cm' with key 'cidr'. Value is currently not used.
