Struct diem_types::validator_verifier::ValidatorVerifier
source · pub struct ValidatorVerifier { /* private fields */ }
Expand description
Supports validation of signatures for known authors with individual voting powers. This struct can be used for all signature verification operations including block and network signature verification, respectively.
Implementations§
source§impl ValidatorVerifier
impl ValidatorVerifier
sourcepub fn new(
address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo>
) -> Self
pub fn new( address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo> ) -> Self
Initialize with a map of account address to validator info and set quorum size to
default (2f + 1
) or zero if address_to_validator_info
is empty.
sourcepub fn new_with_quorum_voting_power(
address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo>,
quorum_voting_power: u64
) -> Result<Self>
pub fn new_with_quorum_voting_power( address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo>, quorum_voting_power: u64 ) -> Result<Self>
Initializes a validator verifier with a specified quorum voting power.
sourcepub fn new_for_testing(
address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo>,
quorum_voting_power: u64,
total_voting_power: u64
) -> Self
pub fn new_for_testing( address_to_validator_info: BTreeMap<AccountAddress, ValidatorConsensusInfo>, quorum_voting_power: u64, total_voting_power: u64 ) -> Self
Initializes a validator verifier with a specified quorum voting power and total power.
sourcepub fn new_single(author: AccountAddress, public_key: Ed25519PublicKey) -> Self
pub fn new_single(author: AccountAddress, public_key: Ed25519PublicKey) -> Self
Helper method to initialize with a single author and public key with quorum voting power 1.
sourcepub fn verify<T: Serialize + CryptoHash>(
&self,
author: AccountAddress,
message: &T,
signature: &Ed25519Signature
) -> Result<(), VerifyError>
pub fn verify<T: Serialize + CryptoHash>( &self, author: AccountAddress, message: &T, signature: &Ed25519Signature ) -> Result<(), VerifyError>
Verify the correctness of a signature of a message by a known author.
sourcepub fn verify_aggregated_struct_signature<T: CryptoHash + Serialize>(
&self,
message: &T,
aggregated_signature: &BTreeMap<AccountAddress, Ed25519Signature>
) -> Result<(), VerifyError>
pub fn verify_aggregated_struct_signature<T: CryptoHash + Serialize>( &self, message: &T, aggregated_signature: &BTreeMap<AccountAddress, Ed25519Signature> ) -> Result<(), VerifyError>
This function will successfully return when at least quorum_size signatures of known authors are successfully verified. Also, an aggregated signature is considered invalid if any of the attached signatures is invalid or it does not correspond to a known author. The latter is to prevent malicious users from adding arbitrary content to the signature payload that would go unnoticed.
sourcepub fn batch_verify_aggregated_signatures<T: CryptoHash + Serialize>(
&self,
message: &T,
aggregated_signature: &BTreeMap<AccountAddress, Ed25519Signature>
) -> Result<(), VerifyError>
pub fn batch_verify_aggregated_signatures<T: CryptoHash + Serialize>( &self, message: &T, aggregated_signature: &BTreeMap<AccountAddress, Ed25519Signature> ) -> Result<(), VerifyError>
This function will try batch signature verification and falls back to normal iterated verification if batching fails.
sourcepub fn check_voting_power<'a>(
&self,
authors: impl Iterator<Item = &'a AccountAddress>
) -> Result<(), VerifyError>
pub fn check_voting_power<'a>( &self, authors: impl Iterator<Item = &'a AccountAddress> ) -> Result<(), VerifyError>
Ensure there is at least quorum_voting_power in the provided signatures and there are only known authors. According to the threshold verification policy, invalid public keys are not allowed.
sourcepub fn get_public_key(&self, author: &AccountAddress) -> Option<Ed25519PublicKey>
pub fn get_public_key(&self, author: &AccountAddress) -> Option<Ed25519PublicKey>
Returns the public key for this address.
sourcepub fn get_voting_power(&self, author: &AccountAddress) -> Option<u64>
pub fn get_voting_power(&self, author: &AccountAddress) -> Option<u64>
Returns the voting power for this address.
sourcepub fn get_ordered_account_addresses_iter(
&self
) -> impl Iterator<Item = AccountAddress> + '_
pub fn get_ordered_account_addresses_iter( &self ) -> impl Iterator<Item = AccountAddress> + '_
Returns an ordered list of account addresses as an Iterator
.
sourcepub fn quorum_voting_power(&self) -> u64
pub fn quorum_voting_power(&self) -> u64
Returns quorum voting power.
