TīmeklisClosures can capture values from their environment in three ways, which directly map to the three ways a function can take a parameter: borrowing immutably, borrowing mutably, and taking ownership. The closure will decide which of these to use based on what the body of the function does with the captured values.

So, thinking of get_random_int and get_random_long in terms of get_random_u32 and get_random_u64 makes it much easier to achieve this. It also makes the code simpler. On 32-bit platforms, …

TīmeklisHi all! I just released alea!It's a crate for generating random numbers. The main goal of this crate is simplicity. Zero dependencies, small code size, and best of all, no more &mut rng everywhere (just call alea::f64() for an f64).alea uses Wyrand as its PRNG, and it's really fast.. This crate isn't trying to compete with larger PRNG crates like …
