[−][src]Enum diesel::serialize::IsNull
Tiny enum to make the return type of ToSql more descriptive
Variants
YesNo data was written, as this type is null
NoThe value is not null
This does not necessarily mean that any data was written to the buffer. For example, an empty string has no data to be sent over the wire, but also is not null.
