Enum Keyword 

Source
#[non_exhaustive]
pub enum Keyword { Null, CurrentDate, CurrentTime, CurrentTimestamp, Default, Custom(DynIden), }
Expand description

Known SQL keywords that can be used as expressions.

If something is not supported here, you can use Keyword::Custom.

Variants (Non-exhaustive)ยง

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
