Errors produced by fallible soft-body construction and simulation operations.

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.

NodeIndexOutOfBounds

A tetrahedral element referenced a node index that does not exist yet.

index is the offending node index and node_count is the number of nodes currently present in the mesh.

Fields

index: u32

node_count: u32

InvalidPoissonsRatio

Poisson’s ratio was outside the physically valid range [0.0, 0.5).

Values >= 0.5 produce a singular / negative Lamé lambda (incompressible limit) and values < 0.0 are unsupported here.

Fields

value: f32

InvalidYoungsModulus

Young’s modulus was not a finite, strictly-positive value.

Fields

value: f32

DegenerateTetrahedron

A tetrahedral element was (near-)degenerate: its rest volume is not a finite, strictly-positive value above the acceptance epsilon.

Such elements have a singular reference shape matrix (Dm), so the deformation gradient and the derived elastic forces are undefined (near-zero stiffness / NaN propagation). volume is the offending rest volume that was computed.

Fields

volume: f32

NodeOffsetOverflow

The flattened GPU node offset overflowed u32 (too many nodes across all soft bodies in a single step).

NoCompatibleAdapter

No compatible GPU adapter could be acquired.

DeviceRequestFailed(String)

Requesting a logical GPU device from the adapter failed.

Trait Implementations

impl Clone for SoftBodyError

fn clone(&self) -> SoftBodyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SoftBodyError

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

Formats the value using the given formatter.

impl Display for SoftBodyError

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

impl Error for SoftBodyError

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 SoftBodyError

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

Equality operator ==.

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

Inequality operator !=.
