Struct MockTransactionHandler 

pub struct MockTransactionHandler { /* private fields */ }

A mocked transaction context: runs one, and only one, transaction, with exactly one root frame (call / open_root_frame panic on a second invocation). Nest further calls as child frames, or use a second transaction.

Implementations

impl MockTransactionHandler

pub fn new(env: Rc<TestEnvironment>) -> MockTransactionHandler

Create a mock transaction handler with the default configuration (see MockTransactionConfig).

Use TestEnvironment::transaction to customize the configuration before creating the handler.

pub fn new_with_config( env: Rc<TestEnvironment>, config: MockTransactionConfig, ) -> MockTransactionHandler

Create a mock transaction handler from an explicit MockTransactionConfig, letting a test configure the context of the mocked transaction.

pub fn abort_transaction(&mut self)

Abort the running transaction, discarding its writes.

Panics unless the transaction is running and its root frame is closed.

pub fn try_commit_transaction(&mut self) -> TryCommitResult

Attempt the two-phase commit of the running transaction.

Panics unless the transaction is running and its root frame is closed.

pub fn call(&mut self, addr: &ContractAddress) -> FrameBuilder<'_>

Convenience: open a root frame targeting the given contract address. Returns a FrameBuilder for configuring and executing the frame.

A transaction has exactly one root frame, so a second call panics; call further contracts via child frames (FrameHandle::child_call, MockInvocationFrame::open_child_frame) or a separate transaction.

pub fn open_root_frame( &mut self, contract_address: ContractAddress, ) -> MockInvocationFrameConfig<'_>

Configure this transaction’s root frame, invoking contract_address.

A transaction has exactly one root frame: calling this (or call) a second time on the same handler panics.

Child frames opened underneath it must name different addresses; see MockInvocationFrame::open_child_frame.

Trait Implementations

impl Drop for MockTransactionHandler

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
