Enum diesel::types::IsNull
[−]
[src]
pub enum IsNull { Yes, No, }
Tiny enum to make the return type of ToSql
more descriptive
Variants
Yes
No data was written, as this type is null
No
The 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.
