Enum BlockchainWriteRequest

Source 
pub enum BlockchainWriteRequest {
    WriteBlock(VerifiedBlockInformation),
    WriteAltBlock(AltBlockInformation),
    PopBlocks(usize),
    ReverseReorg(ChainId),
    FlushAltBlocks,
}
Expand description

A write request to the blockchain database.

Variants§

§

WriteBlock(VerifiedBlockInformation)

Request that a block be written to the database.

Input is an already verified block.

§

WriteAltBlock(AltBlockInformation)

Write an alternative block to the database,

Input is the alternative block.

§

PopBlocks(usize)

A request to pop some blocks from the top of the main chain

Input is the amount of blocks to pop.

This request flushes all alt-chains from the cache before adding the popped blocks to the alt cache.

§

ReverseReorg(ChainId)

A request to reverse the re-org process.

The inner value is the ChainId of the old main chain.

§Invariant

It is invalid to call this with a ChainId that was not returned from BlockchainWriteRequest::PopBlocks.

§

FlushAltBlocks

A request to flush all alternative blocks.
