Functions

func ValidAndSplitDomain

func ValidAndSplitDomain(domain string) ([]string, bool)

Types

type DomainSet

type DomainSet struct {
	// contains filtered or unexported fields
}

func (*DomainSet) Has

func (ss *DomainSet) Has(key string) bool

Has query for a key and return whether it presents in the DomainSet.

type DomainTrie

type DomainTrie[T any] struct {
	// contains filtered or unexported fields
}

DomainTrie contains the main logic for adding and searching nodes for domain segments. support wildcard domain (e.g *.google.com)

func New

func New[T any]() *DomainTrie[T]

New returns a new, empty Trie.

func (*DomainTrie[T]) Foreach

func (t *DomainTrie[T]) Foreach(print func(domain string, data T))

func (*DomainTrie[T]) Insert

func (t *DomainTrie[T]) Insert(domain string, data T) error

Insert adds a node to the trie. Support 1. www.example.com 2. *.example.com 3. subdomain.*.example.com 4. .example.com 5. +.example.com

func (*DomainTrie[T]) NewDomainSet

func (t *DomainTrie[T]) NewDomainSet() *DomainSet

NewDomainSet creates a new *DomainSet struct, from a DomainTrie.

func (*DomainTrie[T]) Optimize

func (t *DomainTrie[T]) Optimize()

func (*DomainTrie[T]) Search

func (t *DomainTrie[T]) Search(domain string) *Node[T]

Search is the most important part of the Trie. Priority as: 1. static part 2. wildcard domain 2. dot wildcard domain

type IPV6

type IPV6 bool

type IpCidrNode

type IpCidrNode struct {
	Mark bool
	// contains filtered or unexported fields
}

func NewIpCidrNode

func NewIpCidrNode(mark bool, maxValue uint32) *IpCidrNode

type IpCidrTrie

type IpCidrTrie struct {
	// contains filtered or unexported fields
}

func NewIpCidrTrie

func NewIpCidrTrie() *IpCidrTrie

func (*IpCidrTrie) AddIpCidr

func (trie *IpCidrTrie) AddIpCidr(ipCidr *net.IPNet) error

func (*IpCidrTrie) AddIpCidrForString

func (trie *IpCidrTrie) AddIpCidrForString(ipCidr string) error

func (*IpCidrTrie) IsContain

func (trie *IpCidrTrie) IsContain(ip net.IP) bool

func (*IpCidrTrie) IsContainForString

func (trie *IpCidrTrie) IsContainForString(ipString string) bool

type Node

type Node[T any] struct {
	// contains filtered or unexported fields
}

Node is the trie's node

func (*Node[T]) Data

func (n *Node[T]) Data() T
