Struct StateWriteArgs 

pub struct StateWriteArgs<'a> {
    pub state_ptr: NonNull<Address>,
    pub new_state_ptr: NonNull<<VariableBytes<RECOMMENDED_STATE_CAPACITY> as IoType>::PointerType>,
    pub new_state_size: u32,
    pub new_state_capacity: u32,
    /* private fields */
}

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: u32

Size of the contents new_state_ptr points to

new_state_capacity: u32

Capacity of the contents new_state_ptr points to

Implementations

impl<'a> StateWriteArgs<'a>

pub fn new( state: &'a Address, new_state: &'a VariableBytes<RECOMMENDED_STATE_CAPACITY>, ) -> Self

Create a new instance.

NOTE: Make sure to query updated sizes of arguments after calling the contract.
