Struct ArbitraryDefault 

pub struct ArbitraryDefault<T>(pub T);

An Arbitrary wrapper that constructs T via Default.

TestCase::Args must implement Arbitrary, but shared-state types like AtomicBool or Mutex<Option<Waker>> typically don’t. Wrap them in ArbitraryDefault to bridge the gap:

testcase!(|args: &mut ArbitraryDefault<AtomicBool>| {
    let ready = &args.0;
    // ...
})

Trait Implementations

impl<'a, A: Default> Arbitrary<'a> for ArbitraryDefault<A>

fn arbitrary(_u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn size_hint(_depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>
