The block environment

Fields

number: Uint<256, 4>

The number of ancestor blocks of this block (block height).

beneficiary: Address

Beneficiary (Coinbase or miner) is a address that have signed the block.

This is the receiver address of all the gas spent in the block.

timestamp: Uint<256, 4>

The timestamp of the block in seconds since the UNIX epoch

gas_limit: u64

The gas limit of the block

basefee: u64

The base fee per gas, added in the London upgrade with EIP-1559

difficulty: Uint<256, 4>

The difficulty of the block

Unused after the Paris (AKA the merge) upgrade, and replaced by prevrandao.

prevrandao: Option<FixedBytes<32>>

The output of the randomness beacon provided by the beacon chain

Replaces difficulty after the Paris (AKA the merge) upgrade with EIP-4399.

Note: prevrandao can be found in a block in place of mix_hash.

blob_excess_gas_and_price: Option<BlobExcessGasAndPrice>

Excess blob gas and blob gasprice

Incorporated as part of the Cancun upgrade via EIP-4844.

Implementations

impl BlockEnv

pub fn set_blob_excess_gas_and_price( &mut self, excess_blob_gas: u64, base_fee_update_fraction: u64, )

Takes blob_excess_gas saves it inside env and calculates blob_fee with BlobExcessGasAndPrice.

Trait Implementations

impl Block for BlockEnv

fn number(&self) -> Uint<256, 4>

The number of ancestor blocks of this block (block height).

fn beneficiary(&self) -> Address

Beneficiary (Coinbase, miner) is an address that has signed the block.

fn timestamp(&self) -> Uint<256, 4>

The timestamp of the block in seconds since the UNIX epoch.

fn gas_limit(&self) -> u64

The gas limit of the block.

fn basefee(&self) -> u64

The base fee per gas, added in the London upgrade with EIP-1559.

fn difficulty(&self) -> Uint<256, 4>

The difficulty of the block.

fn prevrandao(&self) -> Option<FixedBytes<32>>

The output of the randomness beacon provided by the beacon chain.

fn blob_excess_gas_and_price(&self) -> Option<BlobExcessGasAndPrice>

Excess blob gas and blob gasprice.

fn blob_gasprice(&self) -> Option<u128>

See EIP-4844 and calc_blob_gasprice.

fn blob_excess_gas(&self) -> Option<u64>

Return blob_excess_gas header field. See EIP-4844.

impl BlockEnvironment for BlockEnv

fn inner_mut(&mut self) -> &mut BlockEnv

Returns a mutable reference to the inner revm::context::BlockEnv.

impl Clone for BlockEnv

fn clone(&self) -> BlockEnv

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockEnv

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for BlockEnv

fn default() -> BlockEnv

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockEnv

fn deserialize<__D>( __deserializer: __D, ) -> Result<BlockEnv, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for BlockEnv

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BlockEnv

fn eq(&self, other: &BlockEnv) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlockEnv

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BlockEnv

impl StructuralPartialEq for BlockEnv

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
