Variants

Add(AddMutation)

Add new dispatchers to some actors, used for creating materialized views.

Stop(StopMutation)

Stop a set of actors, used for dropping materialized views. Empty dispatchers will be automatically removed.

Update(UpdateMutation)

Update outputs and hash mappings for some dispatchers, used for scaling.

Splits(SourceChangeSplitMutation)

Change the split of some sources.

Pause(PauseMutation)

Pause the dataflow of the whole streaming graph, only used for scaling.

Resume(ResumeMutation)

Resume the dataflow of the whole streaming graph, only used for scaling.

Throttle(ThrottleMutation)

Throttle specific source exec or chain exec.

DropSubscriptions(DropSubscriptionsMutation)

Drop subscription on mv

Combined(CombinedMutation)

Combined mutation.

Implementations

impl Mutation

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Mutation>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Mutation

fn clone(&self) -> Mutation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mutation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Mutation

fn eq(&self, other: &Mutation) -> 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.
