Struct casper_execution_engine::core::runtime::Runtime

pub struct Runtime<'a, R> { /* private fields */ }

Represents the runtime properties of a WASM execution.

Implementations

impl<'a, R> Runtime<'a, R>

where R: StateReader<Key, StoredValue>, R::Error: Into<Error>,

pub fn call_contract( &mut self, contract_hash: ContractHash, entry_point_name: &str, args: RuntimeArgs ) -> Result<CLValue, Error>

Calls contract living under a key, with supplied args.

pub fn call_versioned_contract( &mut self, contract_package_hash: ContractPackageHash, contract_version: Option<ContractVersion>, entry_point_name: String, args: RuntimeArgs ) -> Result<CLValue, Error>

Calls version of the contract living at key, invoking method with supplied args. This function also checks the args conform with the types given in the contract header.

pub fn take_host_buffer(&mut self) -> Option<CLValue>

If host_buffer set, clears the host_buffer and returns value, else None
