Struct IntermediateShardBlocksInfo 

pub struct IntermediateShardBlocksInfo<'a> { /* private fields */ }

Information about a collection of intermediate shard blocks

Implementations

impl<'a> IntermediateShardBlocksInfo<'a>

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. Leaf shards with segments in a block must be children of its shard, ordered by shard index, and segments of the same leaf shard by local segment index. The body root of each block must match its header.

Returns an instance and remaining bytes on success.

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

Iterator over intermediate shard blocks in a collection

pub const fn len(&self) -> usize

Number of intermediate shard blocks

pub const fn is_empty(&self) -> bool

Returns true if there are no intermediate shard blocks

pub fn segments_root(&self) -> Blake3Hash

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

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

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.
