Captures the information necessary to represent struct T { field: F }.
It is then used to build a type-safe Filter<T>, e.g., Filter<OrderId>.
Represents a WHERE clause of the SQL statement. Multiple Filters can be
joined with and and or and also ordered, at which point they become
OrderedFilters.
A
hash map implemented with quadratic probing and SIMD lookup.
A
hash set implemented as a

().
Represents a filter with a an optional LIMIT clause that returns many
results.
Captures the information necessary to represent struct T { field: Option<F> }
which requires additional logic for dealing with NULL values. Like Field<T, F>,
it is used to build a type-safe Filter<T>.
Represents a filter that returns a single results.
