Required Associated Types§
type CallFrameData
Required Methods§
Sourcefn kernel_get_stack_id(&mut self) -> Result<usize, RuntimeError>
fn kernel_get_stack_id(&mut self) -> Result<usize, RuntimeError>
Gets the stack id which is currently being used
Sourcefn kernel_switch_stack(&mut self, id: usize) -> Result<(), RuntimeError>
fn kernel_switch_stack(&mut self, id: usize) -> Result<(), RuntimeError>
Achieves a context switch by switching the underlying callframe/stack
Sourcefn kernel_send_to_stack(
&mut self,
id: usize,
value: &IndexedScryptoValue,
) -> Result<(), RuntimeError>
fn kernel_send_to_stack( &mut self, id: usize, value: &IndexedScryptoValue, ) -> Result<(), RuntimeError>
Moves the objects in a scrypto value from the current call frame to another stack
Sourcefn kernel_set_call_frame_data(
&mut self,
data: Self::CallFrameData,
) -> Result<(), RuntimeError>
fn kernel_set_call_frame_data( &mut self, data: Self::CallFrameData, ) -> Result<(), RuntimeError>
Sets the call frame data for the current call frame
Sourcefn kernel_get_owned_nodes(&mut self) -> Result<Vec<NodeId>, RuntimeError>
fn kernel_get_owned_nodes(&mut self) -> Result<Vec<NodeId>, RuntimeError>
Returns the owned nodes of the current call frame
