Struct BlockContext

pub struct BlockContext<'a> {
    pub opts: Options,
    pub pow_verifier: fn(&BlockHeader) -> Result<(), Error>,
    pub header_allowed: Box<dyn Fn(&BlockHeader) -> Result<(), Error>>,
    pub txhashset: &'a mut TxHashSet,

}

Contextual information required to process a new block and either reject or accept it.

Fields

opts: Options

The options

pow_verifier: fn(&BlockHeader) -> Result<(), Error>

The pow verifier to use when processing a block.

header_allowed: Box<dyn Fn(&BlockHeader) -> Result<(), Error>>

Custom fn allowing arbitrary header validation rules (denylist) to be applied.

txhashset: &'a mut TxHashSet

The active txhashset (rewindable MMRs) to use for block processing.

header_pmmr: &'a mut PMMRHandle<BlockHeader>

The active header MMR handle.

batch: Batch<'a>

The active batch to use for block processing.
