Enum CursorKey 

#[non_exhaustive]
pub enum CursorKey {
    Identity(u64),
    Ordered {
        primary: u64,
        identity: u64,
    },
    Name(String),
}

The immutable ordering key of the last row returned by a page.

Variants (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.

Identity(u64)

A single immutable identity column.

Ordered

An immutable ordinal paired with its identity column.

Fields

primary: u64

Immutable primary ordinal, such as an attempt or sequence.

identity: u64

Identity tiebreaker.

Name(String)

An immutable byte-ordered name column.
