Struct proptest::bits::BitSetStrategy
[−]
[src]
pub struct BitSetStrategy<T: BitSetLike> { /* fields omitted */ }
Generates values as a set of bits between the two bounds.
Values are generated by uniformly setting individual bits to 0 or 1 between the bounds. Shrinking iteratively clears bits.
Methods
impl<T: BitSetLike> BitSetStrategy<T>
[src]
fn new(min: usize, max: usize) -> Self
Create a strategy which generates values where bits between min
(inclusive) and max
(exclusive) may be set.
Due to the generics, the functions in the typed submodules are usually preferable to calling this directly.
