Extension trait providing mutable field access to block, tx, and cfg environments.

[ContextTr] only exposes immutable references for block, tx, and cfg. Cheatcodes like vm.warp(), vm.roll(), vm.chainId() need to mutate these fields.

Required Associated Types

type Spec: Into<SpecId> + Copy + Debug

Specification id type

Bubbled-up from ContextTr::Cfg for convenience and simplified bounds.

Required Methods

fn block_mut(&mut self) -> &mut Self::Block

Mutable reference to the block environment.

fn tx_mut(&mut self) -> &mut Self::Tx

Mutable reference to the transaction environment.

fn cfg_mut(&mut self) -> &mut Self::Cfg

Mutable reference to the configuration environment.

fn cfg_env(&self) -> &CfgEnv<Self::Spec>

Reference to the underlying [CfgEnv].

fn cfg_env_mut(&mut self) -> &mut CfgEnv<Self::Spec>

Mutable reference to the underlying [CfgEnv].

fn db_journal_inner_mut(&mut self) -> (&mut Self::Db, &mut JournaledState)

Mutable reference to the db and the journal inner.

fn journal_inner(&self) -> &JournaledState

Reference to the journal inner.

Provided Methods

fn set_spec_and_gas_params(&mut self, spec: Self::Spec)

Sets the spec and refreshes gas params for the concrete EVM family.

fn set_block(&mut self, block: Self::Block)

Sets block environment.

fn set_tx(&mut self, tx: Self::Tx)

Sets transaction environment.

fn set_cfg(&mut self, cfg: Self::Cfg)

Sets configuration environment.

fn set_journal_inner(&mut self, journal_inner: JournaledState)

Sets journal inner.

fn set_evm(&mut self, evm_env: EvmEnv<Self::Spec, Self::Block>)

Sets EVM environment.

fn tx_clone(&self) -> Self::Tx

Cloned transaction environment.

fn evm_clone(&self) -> EvmEnv<Self::Spec, Self::Block>

Cloned EVM environment (Cfg + Block).

Dyn Compatibility

This trait is not dyn compatible.

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