Expand description

An EVM abstraction of a block header.

Required Associated Types§

Source

type SpecId: Copy

Associated type for the EVM specification identifier (e.g., London, Shanghai).

Required Methods§

Source

fn parent_hash(&self) -> &B256

Returns the hash of the parent block’s header.

Source

fn number(&self) -> BlockNumber

Returns the block number.

Source

fn timestamp(&self) -> u64

Returns the block timestamp.

Source

fn state_root(&self) -> &B256

Returns the state root hash.

Source

fn receipts_root(&self) -> &B256

Returns the receipts root hash of the block.

Source

fn logs_bloom(&self) -> &Bloom

Returns the logs bloom filter of the block

Source

fn to_block_env(&self, spec_id: Self::SpecId) -> BlockEnv

Returns the EVM block environment equivalent to this block header.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
