Struct solana_evm_loader_program::scope::evm::secp256k1::rand::distributions::UnitCircle

[+] Show declaration

pub struct UnitCircle { /* fields omitted */ }

[−] Expand description

Samples uniformly from the edge of the unit circle in two dimensions.

Implemented via a method by von Neumann¹.

Example

use rand::distributions::{UnitCircle, Distribution};

let circle = UnitCircle::new();
let v = circle.sample(&mut rand::thread_rng());
println!("{:?} is from the unit circle.", v)
