Struct sc_finality_grandpa::AuthoritySetChanges

pub struct AuthoritySetChanges<N>(_);

Tracks historical authority set changes. We store the block numbers for the last block of each authority set, once they have been finalized. These blocks are guaranteed to have a justification unless they were triggered by a forced change.

Implementations

impl<N: Ord + Clone> AuthoritySetChanges<N>

pub fn iter_from( &self, block_number: N ) -> Option<impl Iterator<Item = &(u64, N)>>

Returns an iterator over all historical authority set changes starting at the given block number (excluded). The iterator yields a tuple representing the set id and the block number of the last block in that set.

Trait Implementations

impl<N: Clone> Clone for AuthoritySetChanges<N>

fn clone(&self) -> AuthoritySetChanges<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for AuthoritySetChanges<N>

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

Formats the value using the given formatter.

impl<N> Decode for AuthoritySetChanges<N>where Vec<(u64, N)>: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<N> Encode for AuthoritySetChanges<N>where Vec<(u64, N)>: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F: FnOnce(&[u8]) -> R>(&self, f: F) -> R

Convert self to a slice and then invoke the given closure with it.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<N> From<Vec<(u64, N), Global>> for AuthoritySetChanges<N>

fn from(changes: Vec<(u64, N)>) -> AuthoritySetChanges<N>

Converts to this type from the input type.

impl<N: PartialEq> PartialEq<AuthoritySetChanges<N>> for AuthoritySetChanges<N>

fn eq(&self, other: &AuthoritySetChanges<N>) -> bool

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

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

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