Struct quickcheck::StdThreadGen

pub struct StdThreadGen(_);

StdThreadGen is an RNG in thread-local memory.

This is the default RNG used by quickcheck.

Methods

impl StdThreadGen

pub fn new(size: usize) -> StdThreadGen

Returns a new thread-local RNG.

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.
