Struct FungibleTransferArgs 

pub struct FungibleTransferArgs<'a> {
    pub from_ptr: NonNull<<Address as IoType>::PointerType>,
    pub from_size: u32,
    pub from_capacity: u32,
    pub to_ptr: NonNull<<Address as IoType>::PointerType>,
    pub to_size: u32,
    pub to_capacity: u32,
    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 fungible_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 as IoType>::PointerType>

from_size: u32

Size of the contents from_ptr points to

from_capacity: u32

Capacity of the contents from_ptr points to

to_ptr: NonNull<<Address as IoType>::PointerType>

to_size: u32

Size of the contents to_ptr points to

to_capacity: u32

Capacity of the contents to_ptr points to

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
