Expand description

The substrate state machine.

Implementations

Creates new substrate state machine.

Use given cache as storage transaction cache.

The cache will be used to cache storage transactions that can be build while executing a function in the runtime. For example, when calculating the storage root a transaction is build that will be cached.

Set the given parent_hash as the hash of the parent block.

This will be used for improved logging.

Execute a call using the given state backend, overlayed changes, and call executor.

On an error, no prospective changes are written to the overlay.

Note: changes to code will be in place if this call is made again. For running partial blocks (e.g. a transaction at a time), ensure a different method is used.

Returns the SCALE encoded result of the executed function.

Execute a call using the given state backend, overlayed changes, and call executor.

On an error, no prospective changes are written to the overlay.

Note: changes to code will be in place if this call is made again. For running partial blocks (e.g. a transaction at a time), ensure a different method is used.

Returns the result of the executed function either in native representation R or in SCALE encoded representation.
