Struct sprs_rand::rand_distr::UnitDisc
source · [−]pub struct UnitDisc;
Expand description
Samples uniformly from the unit disc in two dimensions.
Implemented via rejection sampling.
Example
use rand_distr::{UnitDisc, Distribution};
let v: [f64; 2] = UnitDisc.sample(&mut rand::thread_rng());
println!("{:?} is from the unit Disc.", v)

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
fn is_in_subset(&self) -> bool
fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
unsafe fn to_subset_unchecked(&self) -> SS
unsafe fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
fn from_subset(element: &SS) -> SP
fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
