#[non_exhaustive]
pub enum Config {
    Random,
    Deterministic,
    Seeded(<TestingRng as SeedableRng>::Seed),
}

Expand description

Type describing a testing_rng configuration.

This is a separate type so that you can pick different defaults, or inspect the configuration before using it.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`Random`

Use a PRNG with a randomly chosen seed.

`Deterministic`

Use a PRNG with a (default) pre-selected seed.

`Seeded(<TestingRng as SeedableRng>::Seed)`

Use a specific seed value for the PRNG.

Implementations

source

impl Config

source

pub fn from_env() -> Option<Self>

Return the testing PRNG from the environment, if one is configured.

Panics

Panics if the environment variable is set to an invalid value.

(If your code must not panic, then it is not test code, and you should not be using this function.)

source

pub fn into_rng(self) -> TestingRng

Consume this Config and return a TestingRng.
