Struct CodeStoreArgs 

pub struct CodeStoreArgs<'a> {
    pub contract_code_ptr: NonNull<Address>,
    pub new_code_ptr: NonNull<<VariableBytes<MAX_CODE_SIZE> as IoType>::PointerType>,
    pub new_code_size: u32,
    pub new_code_capacity: u32,
    /* private fields */
}

Data structure containing expected input for external method invocation, eventually calling code_store() 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

contract_code_ptr: NonNull<Address>

new_code_ptr: NonNull<<VariableBytes<MAX_CODE_SIZE> as IoType>::PointerType>

new_code_size: u32

Size of the contents new_code_ptr points to

new_code_capacity: u32

Capacity of the contents new_code_ptr points to

Implementations

impl<'a> CodeStoreArgs<'a>

pub fn new( contract_code: &'a Address, new_code: &'a VariableBytes<MAX_CODE_SIZE>, ) -> Self

Create a new instance.

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