The default implementation of this protocol is for these two functions to return `nil` as `nil`, a `Boolean` value as a canonical `true` or `false` value (unfortunately, JDBC drivers cannot be relied on to return unique values here!), and for all other objects to be returned as-is. The default implementation of this protocol is for these two functions to return `nil` as `nil`, a `Boolean` value as a canonical `true` or `false` value (unfortunately, JDBC drivers cannot be relied on to return unique values here!), and for all other objects to be returned as-is.
`next.jdbc` makes no assumptions beyond `nil` and `Boolean`, but common extensions here could include converting `java.sql.Timestamp` to `java.time.Instant` for example: `next.jdbc` makes no assumptions beyond `nil` and `Boolean`, but common extensions here could include converting `java.sql.Date` to `java.time.LocalDate` and `java.sql.Timestamp` to `java.time.Instant` for example:
