Struct CodeReadArgs 

pub struct CodeReadArgs<'external_args> {
    pub contract_code_ptr: NonNull<Address>,
    pub code_ptr: NonNull<<VariableBytes<MAX_CODE_SIZE> as IoType>::PointerType>,
    pub code_size: u32,
    pub code_capacity: u32,
    /* private fields */
}

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

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

code_size: u32

Size of the contents code_ptr points to

code_capacity: u32

Capacity of the allocated memory code_ptr points to

Implementations

impl<'external_args> CodeReadArgs<'external_args>

pub fn new( contract_code: &'external_args Address, code: &'external_args mut VariableBytes<MAX_CODE_SIZE>, ) -> Self

Create a new instance.

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