Enum FinalitySignature

pub enum FinalitySignature {
    V1(FinalitySignatureV1),
    V2(FinalitySignatureV2),
}

A validator’s signature of a block, confirming it is finalized.

Clients and joining nodes should wait until the signers’ combined weight exceeds the fault tolerance threshold before accepting the block as finalized.

Variants

V1(FinalitySignatureV1)

Version 1 of the finality signature.

V2(FinalitySignatureV2)

Version 2 of the finality signature.

Implementations

impl FinalitySignature

pub fn block_hash(&self) -> &BlockHash

Returns the block hash of the associated block.

pub fn era_id(&self) -> EraId

Returns the era in which the associated block was created.

pub fn public_key(&self) -> &PublicKey

Returns the public key of the signing validator.

pub fn signature(&self) -> &Signature

Returns the signature over the block hash of the associated block.

pub fn is_verified(&self) -> Result<(), Error>

Returns Ok if the signature is cryptographically valid.

pub fn random(rng: &mut TestRng) -> Self

Available on crate feature testing only.

Returns a random FinalitySignature.

pub fn random_for_block( block_hash: BlockHash, block_height: u64, era_id: EraId, chain_name_hash: ChainNameDigest, rng: &mut TestRng, ) -> Self

Available on crate feature testing only.

Returns a random FinalitySignature for the provided block_hash and era_id.

Trait Implementations

impl Clone for FinalitySignature

fn clone(&self) -> FinalitySignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for FinalitySignature

where FinalitySignatureV1: DataSize, FinalitySignatureV2: DataSize,

const IS_DYNAMIC: bool = true

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

const STATIC_HEAP_SIZE: usize = 0usize

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.

fn estimate_heap_size(&self) -> usize

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

impl Debug for FinalitySignature

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

Formats the value using the given formatter.

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

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

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

Formats the value using the given formatter.

impl From<FinalitySignatureV1> for FinalitySignature

fn from(fs: FinalitySignatureV1) -> Self

Converts to this type from the input type.

impl From<FinalitySignatureV2> for FinalitySignature

fn from(fs: FinalitySignatureV2) -> Self

Converts to this type from the input type.

impl Hash for FinalitySignature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for FinalitySignature

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for FinalitySignature

fn cmp(&self, other: &FinalitySignature) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FinalitySignature

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FinalitySignature

fn partial_cmp(&self, other: &FinalitySignature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for FinalitySignature

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
