Function gcore::msg::send_commit_from_reservation

pub fn send_commit_from_reservation(
    reservation_id: ReservationId,
    handle: MessageHandle,
    destination: ActorId,
    value: u128,
) -> Result<MessageId>

Same as send_commit, but it spends gas from a reservation instead of borrowing it from the gas limit provided with the incoming message.

Examples

use gcore::{exec, msg};

#[no_mangle]
extern "C" fn handle() {
    let reservation_id = exec::reserve_gas(5_000_000, 100).expect("Unable to reserve");
    let msg_handle = msg::send_init().expect("Unable to init");
    msg::send_push(msg_handle, b"Hello,").expect("Unable to push");
    msg::send_push(msg_handle, b" world!").expect("Unable to push");
    msg::send_commit_from_reservation(reservation_id, msg_handle, msg::source(), 42)
        .expect("Unable to commit");
}
