Struct CouponBuyLibfunc

Source
pub struct CouponBuyLibfunc {}
Expand description

Libfunc for buying a coupon for a function.

The cost of the coupon is the cost of running the function (not including the call and ret instructions). The coupon can be used to pay in advance for running the function, and run it later for free (paying only for the call and ret instructions) using coupon_call.
