Possible request types.

Variants

Transact(Vec<TxData>)

Sends inputs via one or more registered handles.

Interest(Interest)

Expresses interest in a named relation.

Uninterest(String)

Expresses that the interest in a named relation has stopped. Once all interested clients have sent this, the dataflow can be cleaned up.

Register(Register)

Registers one or more named relations.

RegisterSource(Source)

A request with the intent of attaching to an external data source that publishes one or more attributes and relations.

CreateAttribute(CreateAttribute)

Creates a named input handle that can be Transacted upon.

AdvanceDomain(Option<String>, Time)

Advances the specified domain to the specified time.

Tick

Requests a domain advance to whatever epoch the server determines is now. Used by clients to enforce a minimum granularity of responses, if inputs happen only infrequently.

CloseInput(String)

Closes a named input handle.

Disconnect

Client has disconnected.

Setup

Requests any setup logic that needs to be executed deterministically across all workers.

Status

Requests a heartbeat containing status information.

Shutdown

Requests orderly shutdown of the system.

Trait Implementations

impl Clone for Request

fn clone(&self) -> Request

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Request

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Request

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Request

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Request

fn cmp(&self, other: &Request) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Request

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

impl PartialOrd for Request

fn partial_cmp(&self, other: &Request) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Request

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Request
