}

Generates a random value in the specified range using the specified algorithm and output type.

Seeds are automatically generated from the system time.

The argument format is [algorithm][bits][type].

• type: i for signed integer [min, max], f for floating-point [min, max).

Examples

use urng::rand;

let val_i32 = rand!(xor32i; 1, 100);
let val_f64 = rand!(mt64f; 0.5, 1.5);
