Shared parameters of the try-runtime commands

Fields

shared_params: SharedParams

Shared parameters of substrate cli.

TODO: this is only needed because try-runtime is embedded in the substrate CLI. It should go away.

runtime: Runtime

The runtime to use.

Must be a path to a wasm blob, compiled with try-runtime feature flag.

Or, existing, indicating that you don’t want to overwrite the runtime. This will use whatever comes from the remote node, or the snapshot file. This will most likely not work against a remote node, as no (sane) blockchain should compile its onchain wasm with try-runtime feature.

wasm_method: WasmExecutionMethod

Type of wasm execution used.

wasmtime_instantiation_strategy: WasmtimeInstantiationStrategy

The WASM instantiation method to use.

Only has an effect when wasm-execution is set to compiled.

heap_pages: Option<u64>

The number of 64KB pages to allocate for Wasm execution. Defaults to [sc_service::Configuration.default_heap_pages].

export_proof: Option<PathBuf>

Path to a file to export the storage proof into (as a JSON). If several blocks are executed, the path is interpreted as a folder where one file per block will be written (named {block_number}-{block_hash}).

overwrite_state_version: Option<StateVersion>

Overwrite the state_version.

Otherwise remote-externalities will automatically set the correct state version.
