Expand description
If the gradient or cost function cannot be evaluated
Computation failed and NaN/Infinite value was obtained
A projection could not be computed numerically
A linear algebra operation failed
The solver reached an unexpected internal state
Returns the lower-level source of this error, if any. Read more
👎Deprecated since 1.42.0:
use the Display impl or to_string()
👎Deprecated since 1.33.0:
replaced by Error::source, which can support downcasting

Tests for self and other values to be equal, and is used by ==.
Tests for !=. The default implementation is almost always sufficient,
and should not be overridden without very good reason.
