Enum Block

pub enum Block<'a> {
    BeaconChain(BeaconChainBlock<'a>),
    IntermediateShard(IntermediateShardBlock<'a>),
    LeafShard(LeafShardBlock<'a>),
}

Block that contains BlockHeader and BlockBody

Variants

BeaconChain(BeaconChainBlock<'a>)

Block corresponds to the beacon chain

IntermediateShard(IntermediateShardBlock<'a>)

Block corresponds to an intermediate shard

LeafShard(LeafShardBlock<'a>)

Block corresponds to a leaf shard

Implementations

impl<'a> Block<'a>

pub fn try_from_bytes( bytes: &'a [u8], shard_kind: ShardKind, ) -> Option<(Self, &'a [u8])>

Try to create a new instance from provided bytes.

bytes should be 16-byte aligned.

Checks internal consistency of header, body, and block, but no consensus verification is done. For unchecked version use Self::try_from_bytes_unchecked().

Returns an instance and remaining bytes on success, None if too few bytes were given, bytes are not properly aligned or input is otherwise invalid.

pub fn is_internally_consistent(&self) -> bool

Check block’s internal consistency.

This is usually not necessary to be called explicitly since full internal consistency is checked by Self::try_from_bytes() internally.

NOTE: This only checks block-level internal consistency, header and block level internal consistency is checked separately.

pub fn try_from_bytes_unchecked( bytes: &'a [u8], shard_kind: ShardKind, ) -> Option<(Self, &'a [u8])>

The same as Self::try_from_bytes(), but for trusted input that skips some consistency checks

pub fn to_owned(self) -> OwnedBlock

Create an owned version of this block

Trait Implementations

impl<'a> Clone for Block<'a>

fn clone(&self) -> Block<'a>

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

Performs copy-assignment from source.

impl<'a> Debug for Block<'a>

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

fn from(value: IntermediateShardBlock<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<LeafShardBlock<'a>> for Block<'a>

fn from(value: LeafShardBlock<'a>) -> Self

Converts to this type from the input type.
