Struct quickcheck::StdGen [−] [src]

pub struct StdGen<R> {
    // some fields omitted
}

StdGen is the default implementation of Gen.

Values of type StdGen can be created with the gen function in this crate.

Methods

`impl<R: Rng> StdGen<R>`

Returns a StdGen with the given configuration using any random number generator.

The size parameter controls the size of random values generated. For example, it specifies the maximum length of a randomly generated vector and also will specify the maximum magnitude of a randomly generated number.

`fn new(rng: R, size: usize) -> StdGen<R>`
