Struct pallet_grandpa::VersionedAuthorityList

pub struct VersionedAuthorityList<'a>(_);

An AuthorityList that is encoded with a version specifier. The encoding version is updated any time the AuthorityList type changes. This ensures that encodings of different versions of an AuthorityList are differentiable. Attempting to decode an authority list with an unknown version will fail.

Trait Implementations

impl<'a> Decode for VersionedAuthorityList<'a>

fn decode<I>(value: &mut I) -> Result<VersionedAuthorityList<'a>, Error>where I: Input,

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<'a> Default for VersionedAuthorityList<'a>

fn default() -> VersionedAuthorityList<'a>

Returns the “default value” for a type.

impl<'a> Encode for VersionedAuthorityList<'a>

fn size_hint(&self) -> usize

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

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

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

fn encode_to<T>(&self, dest: &mut T)where T: Output + ?Sized,

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

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

Convert self to an owned vector.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<'a> From<&'a Vec<(Public, u64), Global>> for VersionedAuthorityList<'a>

fn from( authorities: &'a Vec<(Public, u64), Global> ) -> VersionedAuthorityList<'a>

Converts to this type from the input type.

impl<'a> From<Vec<(Public, u64), Global>> for VersionedAuthorityList<'a>

fn from(authorities: Vec<(Public, u64), Global>) -> VersionedAuthorityList<'a>

Converts to this type from the input type.

impl<'a> Into<Vec<(Public, u64), Global>> for VersionedAuthorityList<'a>

fn into(self) -> Vec<(Public, u64), Global>

Converts this type into the (usually inferred) input type.
