Expand description
Failures raised by the value algebra.
These are the ways an expression can fail to produce a value: an operand
pair no operator accepts, a conversion the target type refuses, a document
shape a clause cannot consume. They describe the data, not the machinery
evaluating it, which is why a subset of them may be resolved to NONE
rather than aborting the query - see Error::is_ignorable.
