Struct diem_crypto::multi_ed25519::MultiEd25519Signature
source · pub struct MultiEd25519Signature { /* private fields */ }
Expand description
Vector of the multi-key signatures along with a 32bit [u8; 4] bitmap required to map signatures with their corresponding public keys.
Note that bits are read from left to right. For instance, in the following bitmap [0b0001_0000, 0b0000_0000, 0b0000_0000, 0b0000_0001], the 3rd and 31st positions are set.

The implementer can override a batch verification implementation
that by default iterates over each signature. More efficient
implementations exist and should be implemented for many schemes.
