Struct PlaygroundTransferArgs

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

Data structure containing expected input for external method invocation, eventually calling playground_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: NonNull<u32>

Size of the contents amount_ptr points to

Implementations

impl PlaygroundTransferArgs

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