Expand description

A trait for getting a random value for a type.

Warning: Be careful when manipulating random values! Therandom method on integers samples them with a uniform distribution, so a value of 1 is just as likely as i32::MAX. By using modulo operations, some of the resulting values can become more likely than others. Use audited crates when in doubt.

Generates a random value.

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
