Module test_utils 

Test and benchmark utilities for generating random data.

This module provides helper functions for tests and benchmarks that need random data generation. These functions replace the functionality previously provided by winter-rand-utils.

no_std Compatibility

This module provides both std-dependent and no_std-compatible functions:

• std required: rand_value, rand_array, rand_vector use the thread-local RNG and require the std feature.
• no_std compatible: seeded_rng, prng_array, prng_vector use deterministic seeded PRNGs and work in no_std environments.

For tests that should run in no_std mode, prefer using seeded_rng to obtain a deterministic RNG instead of rand::rng().

Structs

ContinuousRng

A continuous random number generator that works in no-std contexts.

Functions

prng_array

Generates a deterministic array using a PRNG seeded with the provided seed.

prng_value

Generates a deterministic value using a PRNG seeded with the provided seed.

prng_vector

Generates a deterministic vector using a PRNG seeded with the provided seed.

rand_array

Generates a random array of type T with N elements.

rand_value

Generates a random value of type T using the thread-local random number generator.

rand_vector

Generates a random vector of type T with the specified length.

seeded_rng

Creates a deterministic seeded RNG suitable for tests.
