Struct CodeReadArgs

#[repr(C)]
pub struct CodeReadArgs {
    pub contract_code_ptr: NonNull<Address>,
    pub code_ptr: NonNull<<VariableBytes<MAX_CODE_SIZE> as IoType>::PointerType>,
    pub code_size: *mut u32,
    pub code_capacity: NonNull<u32>,
}

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: *mut u32

Size of the contents code_ptr points to

code_capacity: NonNull<u32>

Capacity of the allocated memory code_ptr points to
