Struct ExampleFtTransferArgs 

pub struct ExampleFtTransferArgs<'a> {
    pub from_ptr: NonNull<Address>,
    pub to_ptr: NonNull<Address>,
    pub amount_ptr: NonNull<<Balance as IoType>::PointerType>,
    pub amount_size: u32,
    pub amount_capacity: u32,
    /* private fields */
}

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

from_ptr: NonNull<Address>

to_ptr: NonNull<Address>

amount_ptr: NonNull<<Balance as IoType>::PointerType>

amount_size: u32

Size of the contents amount_ptr points to

amount_capacity: u32

Capacity of the contents amount_ptr points to

Implementations

impl<'a> ExampleFtTransferArgs<'a>

pub fn new(from: &'a Address, to: &'a Address, amount: &'a Balance) -> Self

Create a new instance.

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