Expand description
A collection of blocks being downloaded.
Implementations§
source§impl<B: BlockT> BlockCollection<B>
impl<B: BlockT> BlockCollection<B>
sourcepub fn insert(
&mut self,
start: NumberFor<B>,
blocks: Vec<BlockData<B>>,
who: PeerId,
)
pub fn insert( &mut self, start: NumberFor<B>, blocks: Vec<BlockData<B>>, who: PeerId, )
Insert a set of blocks into collection.
sourcepub fn needed_blocks(
&mut self,
who: PeerId,
count: u32,
peer_best: NumberFor<B>,
common: NumberFor<B>,
max_parallel: u32,
max_ahead: u32,
) -> Option<Range<NumberFor<B>>>
pub fn needed_blocks( &mut self, who: PeerId, count: u32, peer_best: NumberFor<B>, common: NumberFor<B>, max_parallel: u32, max_ahead: u32, ) -> Option<Range<NumberFor<B>>>
Returns a set of block hashes that require a header download. The returned set is marked as being downloaded.
sourcepub fn ready_blocks(&mut self, from: NumberFor<B>) -> Vec<BlockData<B>>
pub fn ready_blocks(&mut self, from: NumberFor<B>) -> Vec<BlockData<B>>
Get a valid chain of blocks ordered in descending order and ready for importing into
the blockchain.
from
is the maximum block number for the start of the range that we are interested in.
The function will return empty Vec if the first block ready is higher than from
.
For each returned block hash clear_queued
must be called at some later stage.
pub fn clear_queued(&mut self, hash: &B::Hash)
pub fn clear_peer_download(&mut self, who: &PeerId)
