type DiscoverFn ¶

type DiscoverFn func() (SECP256K1, error)

DiscoverFn defines a Ledger discovery function that returns a connected device or an error upon failure. Its allows a method to avoid CGO dependencies when Ledger support is potentially not enabled.

var Discover DiscoverFn = DiscoverDefault

type MockLedger ¶

type MockLedger struct{}

MockLedger is an interface that can be used to create mock [Ledger]. Embed it in another type, and implement the method you want to mock:

type MyMock struct { MockLedger }
func (MyMock) SignSECP256K1(d1, d2 []byte, d3 byte) ([]byte, error) { ... }

func (MockLedger) Close() error

func (MockLedger) GetAddressPubKeySECP256K1(data []uint32, str string) ([]byte, string, error)

func (MockLedger) GetPublicKeySECP256K1(data []uint32) ([]byte, error)

func (MockLedger) SignSECP256K1(d1 []uint32, d2 []byte, d3 byte) ([]byte, error)

type SECP256K1 ¶

type SECP256K1 interface {
	Close() error
	// Returns an uncompressed pubkey
	GetPublicKeySECP256K1([]uint32) ([]byte, error)
	// Returns a compressed pubkey and bech32 address (requires user confirmation)
	GetAddressPubKeySECP256K1([]uint32, string) ([]byte, string, error)
	// Signs a message (requires user confirmation)
	SignSECP256K1([]uint32, []byte, byte) ([]byte, error)
}

SECP256K1 reflects an interface a Ledger API must implement for SECP256K1
