Variables ¶
var ( // ErrCombineMultiple is used when Combine is called with less than two signatures. ErrCombineMultiple = errors.New("must have at least two signatures") // ErrCombineOverlap is used when Combine is called with signatures that have overlapping participation. ErrCombineOverlap = errors.New("overlapping signatures") )
Functions ¶
Types ¶
type Bitfield ¶ added in v0.3.0
type Bitfield struct {
// contains filtered or unexported fields
}
Bitfield is an IDSet implemented by a bitfield. To check if an ID 'i' is present in the set, we simply check if the bit at i-1 is set (because IDs start at 1). This scales poorly if IDs are not sequential.
func BitfieldFromBytes ¶ added in v0.5.0
BitfieldFromBytes creates a bitfield from the given byte slice.
func (Bitfield) Bytes ¶ added in v0.5.0
Bytes returns the raw byte slice containing the data of this bitfield.
func (Bitfield) RangeWhile ¶ added in v0.5.0
RangeWhile calls f for each ID in the set until f returns false.
type Multi ¶ added in v0.5.0
Multi is a set of (partial) signatures.
func Restore ¶ added in v0.5.0
Restore should only be used to restore an existing threshold signature from a set of signatures.
func (Multi[T]) Participants ¶ added in v0.5.0
Participants returns the IDs of replicas who participated in the threshold signature.
func (Multi[T]) RangeWhile ¶ added in v0.5.0
RangeWhile calls f for each ID in the set until f returns false.
