The Host interface.

The set of all callback functions expected by VM instances. This is C realisation of vtable for OOP interface (only virtual methods, no data). Host implementations SHOULD create constant singletons of this (similarly to vtables) to lower the maintenance and memory management cost.

Fields

account_exists: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address) -> bool>

Check account existence callback function.

get_storage: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address, *const evmc_bytes32) -> evmc_bytes32>

Get storage callback function.

set_storage: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address, *const evmc_bytes32, *const evmc_bytes32) -> evmc_storage_status>

Get code size callback function.

get_code_hash: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address) -> evmc_bytes32>

Get code hash callback function.

copy_code: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address, usize, *mut u8, usize) -> usize>

Copy code callback function.

selfdestruct: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_address, *const evmc_address)>

Selfdestruct callback function.

call: Option<unsafe extern "C" fn(*mut evmc_context, *const evmc_message) -> evmc_result>

Call callback function.

get_tx_context: Option<unsafe extern "C" fn(*mut evmc_context) -> evmc_tx_context>
