Functions ¶
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client discovers nodes by querying DNS servers.
func (*Client) NewIterator ¶
NewIterator creates an iterator that visits all nodes at the given tree URLs.
type Config ¶
type Config struct { Timeout time.Duration // timeout used for DNS lookups (default 5s) RecheckInterval time.Duration // time between tree root update checks (default 30min) CacheLimit int // maximum number of cached records (default 1000) RateLimit float64 // maximum DNS requests / second (default 3) ValidSchemes enr.IdentityScheme // acceptable ENR identity schemes (default enode.ValidSchemes) Resolver Resolver // the DNS resolver to use (defaults to system DNS) Logger log.Logger // destination of client log messages (defaults to root logger) }
Config holds configuration options for the client.
type Tree ¶
type Tree struct {
// contains filtered or unexported fields
}
Tree is a merkle tree of node records.
func (*Tree) SetSignature ¶
SetSignature verifies the given signature and assigns it as the tree's current signature if valid.
