Struct solana_runtime::blockhash_queue::BlockhashQueue

pub struct BlockhashQueue { /* fields omitted */ }

Low memory overhead, so can be cloned for every checkpoint

Implementations

impl BlockhashQueue

pub fn new(max_age: usize) -> Self

pub fn hash_height(&self) -> u64

pub fn last_hash(&self) -> Hash
