Errors concerning raw buffers and MeshBuffers.

Variants

IndexOutOfBounds

An index into vertex data is out of bounds.

This error occurs when an index read from an index buffer is out of bounds of the vertex buffer it indexes.

IndexOverflow

The computation of an index causes an overflow.

This error occurs if the result of computing an index overflows the type used to represent indices. For example, if the elements of an index buffer are u8s and an operation results in indices greater than u8::MAX, then this error will occur.

IndexUnaligned

The number of indices in a flat index buffer is incompatible with the arity of the buffer.

This error may occur if a flat index buffer contains a number of indices that is indivisible by the arity of the topology it represents. For example, this may error occur if a triangular index buffer contains a number of indices that is not divisible by three.

ArityConflict

Fields

expected: usize

The expected arity.

actual: usize

The incompatible arity that was encountered.

The arity of a buffer or other data structure is not compatible with an operation.

Trait Implementations

impl Debug for BufferError

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

Formats the value using the given formatter.

impl Display for BufferError

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

Formats the value using the given formatter.

impl Error for BufferError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<BufferError> for GraphError

fn from(error: BufferError) -> Self

Converts to this type from the input type.

impl PartialEq<BufferError> for BufferError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
