Implementations

impl<S: KVGet> BlockTreeSnapshot<S>

pub(crate) fn new(kv_snapshot: S) -> Self

pub(crate) fn blocks_from_height_to_newest( &self, height: BlockHeight, limit: u32, ) -> Result<Vec<Block>, BlockTreeError>

Get a chain of blocks starting from the specified tail block and going towards the newest block, up until the limit.

If tail is None, then the chain starts from genesis instead.

fn blocks_from_newest_to_committed(&self) -> Result<Vec<Block>, BlockTreeError>

Get a chain of blocks from the newest block up to (but not including) the highest committed block, or genesis.

The returned chain goes from blocks of higher height (newest block) to blocks of lower height.
