Struct sp_consensus_grandpa::GrandpaJustification

pub struct GrandpaJustification<Header: HeaderT> {
    pub round: u64,
    pub commit: Commit<Header>,
    pub votes_ancestries: Vec<Header>,
}

A GRANDPA justification for block finality, it includes a commit message and an ancestry proof including all headers routing all precommit target blocks to the commit target block. Due to the current voting strategy the precommit targets should be the same as the commit target, since honest voters don’t vote past authority set change blocks.

This is meant to be stored in the db and passed around the network to other nodes, and are used by syncing nodes to prove authority set handoffs.

Fields

round: u64

commit: Commit<Header>

votes_ancestries: Vec<Header>

Trait Implementations

impl<Header: Clone + HeaderT> Clone for GrandpaJustification<Header>

fn clone(&self) -> GrandpaJustification<Header>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Header: Debug + HeaderT> Debug for GrandpaJustification<Header>

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

Formats the value using the given formatter.

impl<Header: HeaderT> Decode for GrandpaJustification<Header>where
    Commit<Header>: Decode,
    Vec<Header>: Decode,

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

Attempt to deserialise the value from input.

fn decode_into<I>(
    input: &mut I,
    dst: &mut MaybeUninit<Self>
) -> Result<DecodeFinished, Error>where
    I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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<Header: HeaderT> Encode for GrandpaJustification<Header>where
    Commit<Header>: Encode,
    Vec<Header>: Encode,

fn size_hint(&self) -> usize

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

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, Global>

Convert self to an owned vector.

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 encoded_size(&self) -> usize

Calculates the encoded size.

impl<Header: PartialEq + HeaderT> PartialEq<GrandpaJustification<Header>> for GrandpaJustification<Header>

fn eq(&self, other: &GrandpaJustification<Header>) -> 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.

impl<Header> TypeInfo for GrandpaJustification<Header>where
    Commit<Header>: TypeInfo + 'static,
    Vec<Header>: TypeInfo + 'static,
    Header: HeaderT + TypeInfo + 'static,

type Identity = GrandpaJustification<Header>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<Header: HeaderT> EncodeLike<GrandpaJustification<Header>> for GrandpaJustification<Header>where
    Commit<Header>: Encode,
    Vec<Header>: Encode,
