Struct BlockSignaturesV1

pub struct BlockSignaturesV1 { /* private fields */ }

Returns the block hash of the associated block.

pub fn era_id(&self) -> EraId

Returns the era id of the associated block.

pub fn finality_signature( &self, public_key: &PublicKey, ) -> Option<FinalitySignatureV1>

Returns the finality signature associated with the given public key, if available.

pub fn has_finality_signature(&self, public_key: &PublicKey) -> bool

Returns true if there is a signature associated with the given public key.

pub fn finality_signatures( &self, ) -> impl Iterator<Item = FinalitySignatureV1> + '_

Returns the number of signatures in the collection.

pub fn is_empty(&self) -> bool

Returns true if there are no signatures in the collection.

pub fn insert_signature(&mut self, public_key: PublicKey, signature: Signature)

Inserts a new signature.

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

Returns Ok if and only if all the signatures are cryptographically valid.

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

Available on crate feature testing only.

Returns a random BlockSignaturesV1.

Trait Implementations

impl Clone for BlockSignaturesV1

fn clone(&self) -> BlockSignaturesV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for BlockSignaturesV1

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 BlockSignaturesV1

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlockSignaturesV1

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockSignaturesV1

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

Formats the value using the given formatter.

impl From<BlockSignaturesV1> for BlockSignatures

fn from(block_signatures: BlockSignaturesV1) -> Self

Converts to this type from the input type.

impl FromBytes for BlockSignaturesV1

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Hash for BlockSignaturesV1

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 Ord for BlockSignaturesV1

fn cmp(&self, other: &BlockSignaturesV1) -> 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 BlockSignaturesV1

fn eq(&self, other: &BlockSignaturesV1) -> 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 BlockSignaturesV1

fn partial_cmp(&self, other: &BlockSignaturesV1) -> 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 BlockSignaturesV1

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for BlockSignaturesV1

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.
