compute_step_many ~max_steps pvm_state forwards the VM by at most max_step compute tick, yielding if it reaches the maximum number of ticks for a toplevel kernel call. If the VM is expecting input, it gets stuck. If the VM is already stuck, this function may raise an exception. It is more efficient than compute_step if it has to be called for more than one tick, but its resulting pvm_state will be stricly equivalent. Returns a tuple containing the number of executed ticks and the new pvm_state.

compute_step pvm_state forwards the VM by one compute tick. If the VM is expecting input, it gets stuck. If the VM is already stuck, this function may raise an exception. It is strictly equivalent to compute_step_many ~max_step=1 pvm_state.

compute_step_with_debug ~debug_flag pvm_state is exactly compute_step but it has the ability to enable the debugging host functions.

set_input_step input_info message pvm_state forwards the VM by one input tick. If the VM is not expecting input, it gets stuck. If the VM is already stuck, this function may raise an exception. Note at this point the function raises an exception if the VM is not expecting input.

reveal_step reveal_data pvm_state loads the reveal_data in the memory of module of the currently executed function.

If the VM does not expect any reveal data, this function raises an exception.

get_info pvm_state provides a typed view of the current machine state. Should not raise.

get_wasm_version pvm_state returns the current version at which the WASM PVM operates.

compute_step_many_until max_steps reveal_builtins write_debug should_continue pvm_state advances forwards the VM in the same manners as compute_step_many as long as should_continue returns true.

Returns the new state and number of the executed ticks.

IS applied on pvm_state rather than a tree.

/!\ as it allows to redefine the stop condition, this function should not be used in unit test: the test could hide regression if the condition change in the code, but not in the test.

get_output output buffer returns the payload associated with the given output. The result is meant to be deserialized using Sc_rollup_PVM_sem.output_encoding. Raises an exception if the output is not present.
