Trait BlockHashRef

pub trait BlockHashRef {
    type Error: StdError;

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

Trait for immutable access to block hash data. This is typically used for read-only database implementations or when block hash data is pre-loaded.

Required Associated Types

type Error: StdError

Error type for block hash operations

Required Methods

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

Gets block hash by block number.
