Enum RayMeshError 

pub enum RayMeshError {
    NonFiniteInput,
    ZeroDirection,
    InvalidTolerance,
    PositionIndexOutOfRange {
        triangle: usize,
    },
    DegenerateTriangle {
        triangle: usize,
    },
    TriangleIndexOutOfRange {
        triangle: usize,
        triangle_count: usize,
    },
}

Fail-closed reasons a ray/mesh query cannot produce an answer.

Variants

NonFiniteInput

A ray or mesh coordinate is NaN or infinite.

ZeroDirection

The ray direction is exactly zero, so no parametric distance exists.

InvalidTolerance

The tolerance policy is not usable for a parametric query.

PositionIndexOutOfRange

A triangle references a position outside the mesh’s position buffer.

Fields

triangle: usize

Offending triangle.

DegenerateTriangle

A triangle has zero area, so it has no defined ray intersection.

Reported rather than skipped: a silent miss is indistinguishable from empty space.

Fields

triangle: usize

Offending triangle.

TriangleIndexOutOfRange

A candidate triangle index is at or beyond the mesh’s triangle count.

Reported rather than skipped: a broad phase built over a different mesh would otherwise answer “no hit” for triangles it never tested.

Fields

triangle: usize

Offending candidate index.

triangle_count: usize

Triangles in the mesh.

impl Eq for RayMeshError

impl Error for RayMeshError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
