UniformUsize

chunkedge::rand::distr::uniform

Struct UniformUsize 

pub struct UniformUsize { /* private fields */ }
Expand description

The back-end implementing UniformSampler for usize.

§Implementation notes

Sampling a usize value is usually used in relation to the length of an array or other memory structure, thus it is reasonable to assume that the vast majority of use-cases will have a maximum size under u32::MAX. In part to optimise for this use-case, but mostly to ensure that results are portable across 32-bit and 64-bit architectures (as far as is possible), this implementation will use 32-bit sampling when possible.
