Struct evmodin::util::EvmTester

pub struct EvmTester { /* fields omitted */ }

Tester that executes EVM bytecode with MockedHost context and runs set checks.

Implementations

impl EvmTester

pub fn new() -> Self

Create new EvmTester.

pub fn code(self, code: impl Into<Bytecode>) -> Self

Set code to be executed.

pub fn apply_host_fn(
    self,
    host_fn: impl Fn(&mut MockedHost, &Message) + 'static
) -> Self

Queue function that will modify the host before execution.

pub fn revision(self, revision: Revision) -> Self

Set EVM revision for this tester.

pub fn depth(self, depth: u16) -> Self

Set message depth.

pub fn gas(self, gas: i64) -> Self

Set provided gas.

pub fn set_static(self, is_static: bool) -> Self

Set static message flag.

pub fn destination(self, destination: impl Into<Address>) -> Self

Set message destination.

pub fn sender(self, sender: impl Into<Address>) -> Self

Set message sender.

pub fn value(self, value: impl Into<U256>) -> Self

Set message sender.

pub fn gas_used(self, expected_gas_used: i64) -> Self

Check how much gas will be used. Mutually exclusive with EvmTester::gas_left.

pub fn gas_left(self, expected_gas_left: i64) -> Self

Check how much gas will be left after execution. Mutually exclusive with EvmTester::gas_used.

pub fn input(self, input: impl Into<Bytes>) -> Self

Set provided input data.

pub fn status(self, expected_status_code: StatusCode) -> Self

Check returned status.

pub fn status_one_of<const N: usize>(
    self,
    expected_status_code: [StatusCode; N]
) -> Self

Check returned status to be one of these.

pub fn output_value(self, expected_output_data: impl Into<U256>) -> Self

Check output to be equal to provided integer.

pub fn output_data(self, expected_output_data: impl Into<Vec<u8>>) -> Self

Check output data to be equal to provided byte string.

pub fn inspect_output(self, inspect_output_fn: impl Fn(&[u8]) + 'static) -> Self

Inspect output with provided function.

pub fn inspect_host(self, f: impl Fn(&MockedHost, &Message) + 'static) -> Self

Inspect host with provided function.

pub fn inspect(self, f: impl Fn(&MockedHost, &Message, &[u8]) + 'static) -> Self

Inspect host and output with provided function.

pub fn collect_traces(self, doit: bool) -> Self

pub fn check_and_get_result(self) -> Output
