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.

IncompleteTriangle

Triangle index buffer is not divisible by three.

Fields

index_count: usize

PositionIndexOutOfRange

Position index does not exist.

Fields

index: u32

position_count: usize

NormalCount

Non-indexed normals do not align with positions.

Fields

expected: usize

actual: usize

NormalIndexCount

Independently indexed normals do not align with corners.

Fields

expected: usize

actual: usize

NormalIndexOutOfRange

Normal index does not exist.

Fields

index: u32

normal_count: usize

AttributeCount

A channel does not carry one tuple per vertex.

Fields

name: String

Channel name.

expected: usize

Vertices in the mesh.

actual: usize

Vertices the channel covers.

AttributeZeroWidth

A channel declares a zero tuple width, which covers no vertices.

Fields

name: String

Channel name.

AttributeDuplicateName

Two channels share a name, so a lookup would be ambiguous.

Fields

name: String

The repeated name.

AttributeRaggedValues

A corner-indexed channel’s values is not whole tuples.

Fields

name: String

Channel name.

values: usize

Scalars found.

width: usize

Declared tuple width.

AttributeCornerCount

A corner-indexed channel does not have one entry per triangle corner.

Fields

name: String

Channel name.

expected: usize

Triangle corners in the mesh.

actual: usize

Corner entries in the channel.

AttributeCornerIndexOutOfRange

A corner index points past the channel’s values.

Fields

name: String

Channel name.

index: u32

The offending index.

value_count: usize

Tuples available.

AttributePartiallyMapped

A triangle has some corners mapped and some unmapped.

Fields

name: String

Channel name.

triangle: usize

The triangle.

Trait Implementations

impl Clone for MeshValidationError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MeshValidationError

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

impl Eq for MeshValidationError

impl Error for MeshValidationError

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.

impl PartialEq for MeshValidationError

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

Equality operator ==.

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

Inequality operator !=.
