Function libdata::column::register

pub fn register<C: Type>()

Register a type to be used as a column.

Some functions (eg. querying for the data by a user) need the type used as a column to be registered, in addition to implementing the Type trait.

Also, if you want a type that is present on both local and remote endpoint, see the register_endpoint.

#[derive(Clone, Debug, Deserialize, Eq, Ord, Serialize, PartialEq, PartialOrd)]
struct SomeColumn(String);

impl Type for SomeColumn {
    fn name() -> String {
        "some-column".to_owned()
    }
}

column::register::<SomeColumn>();
