Struct FungibleTransferArgs

#[repr(C)]
pub struct FungibleTransferArgs {
    pub from_ptr: NonNull<<Address as IoType>::PointerType>,
    pub from_size: NonNull<u32>,
    pub to_ptr: NonNull<<Address as IoType>::PointerType>,
    pub to_size: NonNull<u32>,
    pub amount_ptr: NonNull<<Balance as IoType>::PointerType>,
    pub amount_size: NonNull<u32>,
}

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: NonNull<u32>

Size of the contents from_ptr points to

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

to_size: NonNull<u32>

Size of the contents to_ptr points to

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

amount_size: NonNull<u32>

Size of the contents amount_ptr points to
