Struct snarkvm_polycommit::optional_rng::OptionalRng[−][src]

pub struct OptionalRng<R>(pub Option<R>);

OptionalRng is a hack that is necessary because Option<&mut R> is not implicitly reborrowed like &mut R is. This causes problems when a variable of type Option<&mut R> is moved (eg, in a loop).

To overcome this, we define the wrapper OptionalRng here that can be borrowed mutably, without fear of being moved.
