Types ¶
type DynamoWatermark ¶
type DynamoWatermark struct {
// contains filtered or unexported fields
}
DynamoWatermark stores the last-signed level in memory
func (*DynamoWatermark) IsSafeToSign ¶
func (mw *DynamoWatermark) IsSafeToSign(keyHash string, chainID string, opMagicByte uint8, level *big.Int) bool
IsSafeToSign returns true if the provided (key, chainID, opMagicByte) tuple has not yet been signed at this or greater levels
type FileWatermark ¶
type FileWatermark struct {
// contains filtered or unexported fields
}
FileWatermark stores the last-signed level in local files
func GetFileWatermark ¶
func GetFileWatermark(file string) *FileWatermark
GetFileWatermark returns a new file watermark manager
func (*FileWatermark) IsSafeToSign ¶
func (wm *FileWatermark) IsSafeToSign(keyHash string, chainID string, opType uint8, level *big.Int) bool
IsSafeToSign returns true if the provided (key, chainID, opType) tuple has not yet been signed at this or greater levels
type IgnoreWatermark ¶
type IgnoreWatermark struct{}
IgnoreWatermark always retruns true
func (*IgnoreWatermark) IsSafeToSign ¶
func (mw *IgnoreWatermark) IsSafeToSign(keyHash string, chainID string, opType uint8, level *big.Int) bool
IsSafeToSign is always true when we're ignoring the watermark
type SessionWatermark ¶
type SessionWatermark struct {
// contains filtered or unexported fields
}
SessionWatermark stores the last-signed level in memory
func GetSessionWatermark ¶
func GetSessionWatermark() *SessionWatermark
GetSessionWatermark returns a new in-memory watermark manager
func (*SessionWatermark) IsSafeToSign ¶
func (mw *SessionWatermark) IsSafeToSign(keyHash string, chainID string, opType uint8, level *big.Int) bool
IsSafeToSign returns true if the provided (key, chainID, opType) tuple has not yet been signed at this or greater levels
type Watermark ¶
type Watermark interface {
// IsSafeToSign returns true if the provided (key, chainID, opType) tuple has
// not yet been signed at this or greater levels
IsSafeToSign(keyHash string, chainID string, opMagicByte uint8, level *big.Int) bool
}
Watermark stores the last (key, level, chainID) tuple that has been signed and fails if you attempt to sign the same or lesser level for that tuple
func GetDynamoWatermark ¶
GetDynamoWatermark returns a new dynamo watermark manager
func GetIgnoreWatermark ¶
func GetIgnoreWatermark() Watermark
GetIgnoreWatermark that will always return true
