TupleDecodeFailed

A FoundationDB tuple could not be decoded.

TupleShapeInvalid

A tuple did not match the required domain shape.

ValueDecodeFailed

A stored value could not be decoded.

IntegerOverflow

Checked arithmetic or numeric conversion overflowed.

InvalidPageSize

A requested page size was zero or outside policy.

InvalidRangePrefix

A prefix could not produce a bounded exclusive range end.

MetadataKeyInvalid

A tenant metadata key could not be constructed.

👎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
