Struct NodeDescriptor 

pub struct NodeDescriptor {
    pub id: NodeId,
    pub descriptor: String,
    pub configuration: Option<Configuration>,
}

Describes an node of the graph

id : PrintSink
descriptor: file://./target/release/counter_source.yaml
configuration:
  start: 10

Fields

id: NodeId

descriptor: String

configuration: Option<Configuration>

Implementations

impl NodeDescriptor

pub fn from_yaml(data: &str) -> Result<Self>

Creates a new NodeDescriptor from its YAML representation.

Errors

A variant error is returned if deserialization fails.

pub fn from_json(data: &str) -> Result<Self>

Creates a new NodeDescriptor from its JSON representation.

Errors

A variant error is returned if deserialization fails.

pub fn to_json(&self) -> Result<String>

Returns the JSON representation of the NodeDescriptor.

Errors

A variant error is returned if serialization fails.

pub fn to_yaml(&self) -> Result<String>

Returns the YAML representation of the NodeDescriptor.

Errors

A variant error is returned if serialization fails.

pub async fn flatten( self, id: NodeId, links: &mut Vec<LinkDescriptor>, global_configuration: Option<Configuration>, ancestors: &mut Vec<String>, ) -> Result<Vec<OperatorDescriptor>>

Flattens the NodeDescriptor by loading all the composite operators

Errors

A variant error is returned if loading operators fails. Or if the node does not contains an operator

pub async fn load_source( self, global_configuration: Option<Configuration>, ) -> Result<SourceDescriptor>

Loads the source from the NodeDescriptor

Errors

A variant error is returned if loading source fails. Or if the node does not contains an source

pub async fn load_sink( self, global_configuration: Option<Configuration>, ) -> Result<SinkDescriptor>

Loads the sink from the NodeDescriptor

Errors

A variant error is returned if loading sink fails. Or if the node does not contains an sink

Trait Implementations

impl Clone for NodeDescriptor

fn clone(&self) -> NodeDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeDescriptor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeDescriptor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NodeDescriptor

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

Formats the value using the given formatter.

impl PartialEq for NodeDescriptor

fn eq(&self, other: &NodeDescriptor) -> 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 NodeDescriptor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
