Function malachite_base::chars::random::random_char_inclusive_range
source · [−]pub fn random_char_inclusive_range(
seed: Seed,
a: char,
b: char
) -> RandomCharRangeⓘNotable traits for RandomCharRangeimpl Iterator for RandomCharRange type Item = char;
Expand description
Uniformly generates random char
s in the closed interval $[a, b]$.
$a$ must be less than or equal to $b$.
$$ P(x) = \begin{cases} \frac{1} {\mathrm{char\_to\_contiguous\_range(b)}-\mathrm{char\_to\_contiguous\_range(a)} +1} & \text{if} \quad a \leq x < b \\ 0 & \text{otherwise} \end{cases} $$
The output length is infinite.
Expected complexity per iteration
Constant time and additional memory.
Panics
Panics if $a > b$.
