Trait BlockHash

pub trait BlockHash {
    type Error: StdError;

    // Required method
    fn block_hash(&mut self, number: u64) -> Result<B256, Self::Error>;
}

Trait for mutable access to block hash data. This is typically used for database implementations that may cache or lazily load block hashes.

Required Associated Types

type Error: StdError

Error type for block hash operations

Required Methods

fn block_hash(&mut self, number: u64) -> Result<B256, Self::Error>

Gets block hash by block number.
