Struct PendingBlock 

pub struct PendingBlock<N: Network>(/* private fields */);

Wrapper for a block that has a valid subDAG, but where the block header, solutions, and transmissions have not been verified yet.

This type is created by Ledger::check_block_subdag and consumed by Ledger::check_block_content.

Trait Implementations

impl<N: Clone + Network> Clone for PendingBlock<N>

fn clone(&self) -> PendingBlock<N>

Returns a duplicate of the value.
