Struct DataflowLayout 

pub struct DataflowLayout {
    pub inputs: HashSet<Uuid>,
    pub outputs: HashSet<Uuid>,
    pub queries: HashSet<Uuid>,
    pub queryables: HashSet<Uuid>,
    pub labels: HashMap<Uuid, String>,
    pub nodes: HashMap<Uuid, HashSet<Uuid>>,
}

Represents a flattened dataflow layout

Fields

inputs: HashSet<Uuid>

Inputs present in the dataflow

outputs: HashSet<Uuid>

Outputs present in the dataflow

queries: HashSet<Uuid>

Queries present in the dataflow

queryables: HashSet<Uuid>

Queryables present in the dataflow

labels: HashMap<Uuid, String>

Labels for nodes and IO, useful for debugging and visualization

nodes: HashMap<Uuid, HashSet<Uuid>>

Nodes representation with their IO, useful for debugging and visualization

Implementations

impl DataflowLayout

pub fn new() -> Self

Creates a new empty dataflow layout

pub async fn node<T>( &mut self, label: impl Into<String>, builder_function: impl AsyncFnOnce(&mut NodeIOBuilder) -> T, ) -> (NodeLayout, T)

Adds a new node to the dataflow layout, providing its label and a builder function for its IO. For convenience, the node layout is returned, together with the result of the builder function.

pub fn label(&self, uuid: impl Into<Uuid>) -> String

Access the label of an entity in the dataflow layout (node, input, output, query, queryable)

pub fn build(self) -> Arc<Self>

Build the dataflow layout by making it immutable and returning an Arc

Trait Implementations

impl Debug for DataflowLayout

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

Formats the value using the given formatter.

impl Default for DataflowLayout

fn default() -> Self

Returns the “default value” for a type.
