Struct StateWriteArgs

#[repr(C)]
pub struct StateWriteArgs {
    pub state_ptr: NonNull<Address>,
    pub new_state_ptr: NonNull<<VariableBytes<RECOMMENDED_STATE_CAPACITY> as IoType>::PointerType>,
    pub new_state_size: NonNull<u32>,
}

Data structure containing expected input for external method invocation, eventually calling state_write() on the other side by the host.

This can be used with Env, though there are helper methods on this provided by extension trait that allow not dealing with this struct directly in simpler cases.

Fields

state_ptr: NonNull<Address>

new_state_ptr: NonNull<<VariableBytes<RECOMMENDED_STATE_CAPACITY> as IoType>::PointerType>

new_state_size: NonNull<u32>

Size of the contents new_state_ptr points to

Implementations
