Struct ClosedUnitF64 

pub struct ClosedUnitF64(/* private fields */);

A finite f64 value in the closed interval [0.0, 1.0].

Used for parameters that represent interpolation weights or trade-offs where the boundary values are valid (e.g., Barnes-Hut theta where 0.0 means “maximum accuracy” and 1.0 means “maximum speed”).

Construction

use cugraph::params::ClosedUnitF64;

let theta = ClosedUnitF64::new(0.5).unwrap();
assert_eq!(theta.get(), 0.5);

// Boundary values are accepted (closed interval):
assert!(ClosedUnitF64::new(0.0).is_ok());
assert!(ClosedUnitF64::new(1.0).is_ok());

Implementations

impl ClosedUnitF64

pub fn new(value: f64) -> Result<Self>

Create a new ClosedUnitF64 from an f64.

Errors

Returns ErrorKind::InvalidInput if value is not in the closed interval [0.0, 1.0] or is not finite.

pub const fn get(self) -> f64

Get the underlying f64 value.
