Struct proptest::array::UniformArrayStrategy

pub struct UniformArrayStrategy<S, T> { /* private fields */ }

A Strategy which generates fixed-size arrays containing values drawn from an inner strategy.

T must be an array type of length 1 to 32 whose values are produced by strategy S. Instances of this type are normally created by the various uniformXX functions in this module.

This is mainly useful when the inner strategy is not Copy, precluding expressing the strategy as [myStrategy; 32], for example.

Example

use proptest::prelude::*;

proptest! {
  #[test]
  fn test_something(a in prop::array::uniform32(1u32..)) {
    let unexpected = [0u32;32];
    // `a` is also a [u32;32], so we can compare them directly
    assert_ne!(unexpected, a);
  }
}

Implementations

impl<S, T> UniformArrayStrategy<S, T>

pub fn new(strategy: S) -> Self

Directly create a UniformArrayStrategy.

This is only intended for advanced use, since the only way to specify the array size is with the turbofish operator and explicitly naming the type of the values in the array and the strategy itself.

Prefer the uniformXX functions at module-level unless something precludes their use.
