[−][src]Struct snarkos_polycommit::optional_rng::OptionalRng
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.
