Struct StateCompareAndWriteArgs 

pub struct StateCompareAndWriteArgs<'external_args> { /* private fields */ }

Data structure containing expected input for external method invocation, eventually calling state_compare_and_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.

Implementations

impl<'external_args> StateCompareAndWriteArgs<'external_args>

pub fn new( state: &'external_args Address, old_state: &'external_args VariableBytes<RECOMMENDED_STATE_CAPACITY>, new_state: &'external_args VariableBytes<RECOMMENDED_STATE_CAPACITY>, ok_result: &'external_args mut MaybeUninit<Bool>, ) -> Self

Create a new instance.

NOTE: Make sure to query updated sizes of outputs with *_size() getters after calling the contract.
