Enum Sight

#[non_exhaustive]
pub enum Sight {
    Visible {
        through: Point3,
        triangle: usize,
    },
    Hidden {
        occluders: Vec<usize>,
    },
    Undecided,
}

What can be proven about the view from an eye to a target.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Visible

Some part of the target is in view.

Fields

through: Point3

The ray from the eye through this point is the witness.

triangle: usize

The target triangle it crosses, strictly inside, before any blocker.

Hidden

No part of the target is in view.

Fields

occluders: Vec<usize>

Indices of the blockers the argument used, ascending.

Undecided

Neither could be proven within the budget.

Trait Implementations

impl Clone for Sight

fn clone(&self) -> Sight

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sight

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Sight

fn eq(&self, other: &Sight) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
