Function forest_filecoin::ipld::util::stream_chain

pub fn stream_chain<DB: Blockstore, T: Iterator<Item = Tipset> + Unpin>(
    db: DB,
    tipset_iter: T,
    stateroot_limit: i64,
) -> ChainStream<DB, T>

Stream all blocks that are reachable before the stateroot_limit epoch in a depth-first fashion. After this limit, only block headers are streamed. Any dead links are reported as errors.

Arguments

• db - A database that implements Blockstore interface.
• tipset_iter - An iterator of Tipset, descending order $child -> $parent.
• stateroot_limit - An epoch that signifies how far back we need to inspect tipsets, in-depth. This has to be pre-calculated using this formula: $cur_epoch - $depth, where $depth is the number of [Tipset] that needs inspection.
