Struct quickcheck::StdThreadGen
source · pub struct StdThreadGen(_);Expand description
StdThreadGen is an RNG in thread-local memory.
This is the default RNG used by quickcheck.
Implementations
sourceimpl StdThreadGen
impl StdThreadGen
sourcepub fn new(size: usize) -> 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.
