Struct casper_node::types::FinalitySignature

pub struct FinalitySignature {
    pub block_hash: BlockHash,
    pub era_id: EraId,
    pub signature: Signature,
    pub public_key: PublicKey,
}

A validator's signature of a block, to confirm it is finalized. Clients and joining nodes should wait until the signers' combined weight exceeds their fault tolerance threshold before accepting the block as finalized.

Fields

block_hash: BlockHash

Hash of a block this signature is for.

era_id: EraId

Era in which the block was created in.

signature: Signature

Signature over the block hash.

public_key: PublicKey

Public key of the signing validator.

Implementations

impl FinalitySignature

pub fn new(
    block_hash: BlockHash,
    era_id: EraId,
    secret_key: &SecretKey,
    public_key: PublicKey,
    rng: &mut NodeRng
) -> Self

Create an instance of FinalitySignature.

pub fn verify(&self) -> Result<()>

Verifies whether the signature is correct.

Trait Implementations

impl Clone for FinalitySignature

pub fn clone(&self) -> FinalitySignature

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DataSize for FinalitySignature

pub const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

pub const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

pub fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for FinalitySignature

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FinalitySignature

pub fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for FinalitySignature

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for FinalitySignature

impl PartialEq<FinalitySignature> for FinalitySignature

pub fn eq(&self, other: &FinalitySignature) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &FinalitySignature) -> bool

This method tests for !=.

impl Serialize for FinalitySignature

pub fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
