Trait RandomSource 

pub trait RandomSource: RngCore {
    // Provided method
    fn reseed(&mut self, seed: u64) { ... }
}

A pluggable source of randomness for a SimEnv.

The RngCore supertrait means env.rng().sample(dist) keeps working for every source. Implementations that are seed-based override reseed so that SimEnv::set_seed can restart their stream; sources that are not seed-based (e.g. a recorded-data feed) may keep the default, which panics — consistent with the crate’s “programming error ⇒ panic” policy.

Provided Methods

fn reseed(&mut self, seed: u64)

Re-seed the source deterministically, restarting its stream.

The default implementation panics. Override it for seed-based sources.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
