Struct MockInvocationFrame 

pub struct MockInvocationFrame { /* private fields */ }

One open invocation frame in a mocked transaction. Drive it with execute, then read the outcome with result. Prefer the fluent crate::frame_builder::FrameBuilder API unless a test needs this level of control.

Implementations

impl MockInvocationFrame

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

Configure a child frame of this one, invoking contract_address.

The address must differ from every frame already open on the stack: the test FFI admits mock frames under the same reentrance rule production applies to Invoke, so an address that already has an active frame is refused and build() panics unrecoverably. Frames that have already finished, and frames in other transactions, do not count — only the ones open at the same time.

pub fn execute( &mut self, lambda: impl FnOnce(&mut Self) -> FrameAction + UnwindSafe, ) -> &mut Self

Run lambda as this frame’s contract code, mapping panics out of it to frame outcomes. Unrecoverable InvokeError payloads (harness misuse, FFI refusals) propagate instead. The returned FrameAction closes the frame or leaves it open for another execute.

pub fn result(&mut self) -> FrameResult

The closed frame’s FrameResult. Panics if the frame is still open.

Trait Implementations

impl Drop for MockInvocationFrame

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.
