Why an attribute value could not be decoded into geometry.

at fields locate the offending value inside the attribute value, for example points[3][1] or faceVertexIndices[7].

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.

WrongShape

A value does not have the JSON shape the attribute requires.

Fields

at: String

expected: &'static str

What was expected, for example "array of 3 numbers".

MissingField

A required field of an object-valued attribute is absent.

Fields

field: &'static str

IndexOutOfRange

A vertex index points past the end of the vertex list.

Fields

at: String

index: u32

vertex_count: usize

NotTriangles

A triangle index list whose length is not a multiple of three.

Fields

index_count: usize

NonTriangleFace

A face that is not a triangle, from faceVertexCounts.

Fields

face: usize

vertex_count: u64

CountMismatch

Per-face or per-curve vertex counts that do not add up to the number of indices or points they describe.

Fields

field: &'static str

counted: u64

available: usize

CurveTooShort

A curve with fewer than two vertices, which cannot form a line.

Fields

curve: usize

vertex_count: u64

NonAffineTransform

A 4×4 transform whose last column is not (0, 0, 0, 1).

Fields

last_column: [f64; 4]

UnknownToken

A string that is not one of the tokens the attribute allows.

Fields

at: String

token: String

expected: &'static str

The allowed tokens, for example "inherited or invisible".

LengthMismatch

Two lists that must have one entry each, such as point colours and positions, differ in length.

Fields

field: &'static str

len: usize

expected: usize

InvalidBase64

A base64 string is malformed.

Fields

at: String

reason: String

ByteLength

Decoded binary data is not a whole number of elements.

Fields

at: String

bytes: usize

element_size: usize

InvalidPcd

A PCD header or data section is malformed or truncated.

Fields

reason: String

UnsupportedPcd

A well-formed PCD file in a layout the upstream viewer cannot read either, such as f64 coordinates or DATA binary_lz4.

Fields

reason: String

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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 DecodeError

fn eq(&self, other: &DecodeError) -> 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.
