Function random_vec

pub fn random_vec<T: Random>(items_count: u32) -> Vec<T>

Generates a vector of items that implement the Random trait.

#[cfg(any(feature = "test", feature = "all"))]
use cs_utils::test::random_vec;
// Note: `traits` or `all` crate features must be enabled to access the `traits` module.
#[cfg(any(feature = "traits", feature = "all"))]
