Enum LockType

#[non_exhaustive]
pub enum LockType {
    Update,
    NoKeyUpdate,
    Share,
    KeyShare,
}

List of lock types that can be used in select statement

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.

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
