Expand description

Information about a collection of leaf shard blocks

Implementations§

Source§

impl<'a> LeafShardBlocksInfo<'a>

Source

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

Create an instance from provided bytes.

bytes do not need to be aligned, but padding in the layout depends on their address and must be present in full.

Blocks must be ordered by shard index, and blocks of the same shard by block number and by local segment index of own segments. The body root of each block must match its header.

Returns an instance and remaining bytes on success.

Source

pub fn iter( &self, ) -> impl ExactSizeIterator<Item = LeafShardBlockInfo<'a>> + TrustedLen + use<'a>

Iterator over leaf shard blocks in a collection

Source

pub const fn len(&self) -> usize

Number of leaf shard blocks

Source

pub const fn is_empty(&self) -> bool

Returns true if there are no leaf shard blocks

Source

pub fn segments_root(&self) -> Blake3Hash

Compute the root of segments of the leaf shard blocks info.

Returns the default value for an empty collection of shard blocks.

Source

pub fn headers_root(&self) -> Blake3Hash

Compute the root of child block roots, which the header stores.

Returns the default value for an empty collection of shard blocks.
