Enum EventKind 

#[non_exhaustive]
pub enum EventKind {
    Insert,
    Update,
    Delete,
}

Event kind for filtering subscription events.

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.

Insert

INSERT — new row created.

Update

UPDATE — existing row modified.

Delete

DELETE — row removed.

fn clone(&self) -> EventKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for EventKind

fn from(kind: EventKind) -> Self

Converts to this type from the input type.

impl Hash for EventKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl PartialEq for EventKind

fn eq(&self, other: &EventKind) -> bool

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.
