Struct rand::distributions::uniform::UniformChar

[+] Show declaration

pub struct UniformChar { /* fields omitted */ }

[−] Expand description

The back-end implementing UniformSampler for char.

Unless you are implementing UniformSampler for your own type, this type should not be used directly, use Uniform instead.

This differs from integer range sampling since the range 0xD800..=0xDFFF are used for surrogate pairs in UCS and UTF-16, and consequently are not valid Unicode code points. We must therefore avoid sampling values in this range.
