Struct Spawn

pub struct Spawn {
    pub expression: Option<Expression>,
    pub pacing: PacingType,
    pub condition: Option<Expression>,
}

Information on the spawn behavior of a stream

Fields

expression: Option<Expression>

The expression needs to be evaluated whenever the stream with this Spawn template is supposed to be spawned. The result of the evaluation constitutes the respective parameters.

pacing: PacingType

The timing of when a new instance could be created assuming the spawn condition evaluates to true.

condition: Option<Expression>

The spawn condition. If the condition evaluates to false, the stream will not be spawned.

Trait Implementations

impl Clone for Spawn

fn clone(&self) -> Spawn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Spawn

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

Formats the value using the given formatter.

impl Default for Spawn

fn default() -> Spawn

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Spawn

fn deserialize<__D>( __deserializer: __D, ) -> Result<Spawn, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Spawn

fn eq(&self, other: &Spawn) -> 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 Serialize for Spawn

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
