random_int

bento_kit::id

Function random_int 

Source 
pub fn random_int(min: i64, max: i64) -> i64
Available on crate feature id only.
Expand description

Generate a random integer in the half-open range [min, max).

Mirrors id.randomInt(min, max) from the Node library.

ยงPanics

Panics if min >= max (consistent with rand::Rng::gen_range).

let n = bento_kit::id::random_int(0, 10);
assert!((0..10).contains(&n));
