# Errors

> USearch for C#

Every failure arrives as a `USearchException` carrying a `Status`, one enumerator per `usearch_status_*_k`, such as `ShapeMismatch`, `Io`, `Unsupported`, or `InvalidArgument`.
Width and geometry checks belong to the library, which sees every row view's `columns`; the binding checks only what the C interface cannot see, like a key count against the rows it accompanies, a softmax carry against the queries, or a negative `wanted`.

The closed sets spell themselves through the library's own name tables, so a message reads `usearch: shape-mismatch: ...` and parsing user text never restates a table:

```csharp
string spelled = Status.ShapeMismatch.Name();          // "shape-mismatch"
bool known = Names.TryParse("bf16", out Scalar scalar);
```
