EVM gas calculation utilities.

instructions

EVM opcode implementations.

interpreter

interpreter_action

opcode

EVM opcode definitions and utilities.

Macros

as_isize_saturated

Converts a U256 value to a isize, saturating to isize::MAX if the value is too large.

as_u64_saturated

Converts a U256 value to a u64, saturating to MAX if the value is too large.

as_usize_or_fail

Converts a U256 value to a usize, failing the instruction if the value is too large.

as_usize_or_fail_ret

Converts a U256 value to a usize and returns ret, failing the instruction if the value is too large.

as_usize_saturated

Converts a U256 value to a usize, saturating to MAX if the value is too large.

check

Check if the SPEC is enabled, and fail the instruction if it is not.

gas

Records a gas cost and fails the instruction if it would exceed the available gas.

gas_or_fail

Same as gas!, but with gas as an option.

pop

Pops U256 values from the stack. Fails the instruction if the stack is too small.

pop_address

Pops Address values from the stack. Fails the instruction if the stack is too small.

pop_address_ret

Pop Address values from the stack, returns ret on stack underflow.

pop_ret

Pops U256 values from the stack, and returns ret. Fails the instruction if the stack is too small.

pop_top

Pops U256 values from the stack, and returns a reference to the top of the stack. Fails the instruction if the stack is too small.

push

Pushes a B256 value onto the stack. Fails the instruction if the stack is full.

push_b256

Pushes B256 values onto the stack. Fails the instruction if the stack is full.

refund

Records a gas refund.

require_eof

Error if the current call is executing EOF.

require_init_eof

Error if not init eof call.

require_non_staticcall

Fails the instruction if the current call is static.

resize_memory

Resizes the interpreter memory if necessary. Fails the instruction if the memory or gas limit is exceeded.

return_error

return_ok

return_revert

Structs

DummyHost

A dummy Host implementation.

FunctionReturnFrame

Function return frame. Needed information for returning from a function.

FunctionStack

Function Stack

LoadAccountResult

Result of the account load from Journal state.

SStoreResult

Represents the result of an sstore operation.

SelfDestructResult

Result of a selfdestruct instruction.

Enums

CreateScheme

Create scheme.

InstructionResult

SuccessOrHalt

Constants

MAX_CODE_SIZE

EIP-170: Contract code size limit By default limit is 0x6000 (~25kb)

MAX_INITCODE_SIZE

EIP-3860: Limit and meter initcode

Traits

Host

EVM context host.
