Configuration for run.

Fields

virtual_machine: HostVmPrototype

Virtual machine to be run.

function_to_call: &'a str

Name of the function to be called.

parameter: TParams

Parameter of the call, as an iterator of bytes. The concatenation of bytes forms the actual input.

storage_main_trie_changes: TrieDiff

Initial state of Success::storage_changes. The changes made during this execution will be pushed over the value in this field.

storage_proof_size_behavior: StorageProofSizeBehavior

Behavior if the ext_storage_proof_size_storage_proof_size_version_1 host function is called.

See the documentation of StorageProofSizeBehavior.

max_log_level: u32

Maximum log level of the runtime.

Note: This value is opaque from the point of the view of the client, and the runtime is free to interpret it the way it wants. However, usually values are: 0 for “off”, 1 for “error”, 2 for “warn”, 3 for “info”, 4 for “debug”, and 5 for “trace”.

calculate_trie_changes: bool

If true, then StorageChanges::trie_changes_iter_ordered will return Some. Passing None requires fewer calculation and fewer storage accesses.
