Types

type Config

type Config struct {
	// Logger is used to log the operation of the device finder.  It must not be
	// nil.
	Logger *slog.Logger

	// ProfileDB is used to find the profiles.  It must not be nil.
	ProfileDB profiledb.Interface

	// HumanIDParser is used to normalize and parse human-readable device
	// identifiers.  It must not be nil.
	HumanIDParser *agd.HumanIDParser

	// Server contains the data of the server for which the profiles are found.
	// It must not be nil.
	Server *agd.Server

	// DeviceDomains, if any, provides the domain names to use for looking up
	// device ID from TLS server names.
	DeviceDomains []string
}

Config is the configuration structure for the default device finder.

type Default

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

Default is the default device finder.

TODO(a.garipov): Use.

func NewDefault

func NewDefault(c *Config) (f *Default)

NewDefault returns a new default device finder. c must be valid and non-nil.

func (*Default) Find

func (f *Default) Find(
	ctx context.Context,
	req *dns.Msg,
	raddr netip.AddrPort,
	laddr netip.AddrPort,
) (r agd.DeviceResult)

Find implements the agd.DeviceFinder interface for *Default. ctx must contain *dnsserver.RequestInfo.
