Struct Builder 

Source 
pub struct Builder<Input, Output, Error, Context, NodeTypes = (), NodeIOETypes = ()>
where
    Input: Send,
    Error: Send,
    Context: Send,
{ /* private fields */ }
Expand description

Builder for SequentialFlow.

This builder ensures:

  • Input into the flow can be converted into the input of the first node
  • output of the last node can be converted into the Output of the flow
  • error of all nodes can be converted into the Error of the flow
  • output of a previous node can be converted into the input of the next node

See also SequentialFlow.

Implementations§

Source§

impl<Input, Output, Error, Context> Builder<Input, Output, Error, Context>
where Input: Send, Error: Send, Context: Send,

Source

pub fn new() -> Self

Creates a new empty builder for SequentialFlow.

Source

pub fn add_node<NodeType, NodeInput, NodeOutput, NodeError>( self, node: NodeType, ) -> Builder<Input, Output, Error, Context, (NodeType,), ((), (NodeInput, NodeOutput<NodeOutput>, NodeError))>
where Input: Into<NodeInput>, NodeError: Into<Error>, NodeType: Node<NodeInput, NodeOutputStruct<NodeOutput>, NodeError, Context> + Clone + Send + Sync, NodeInput: Send,

Adds a new node.

The new node must satisfy:

  • Self: Node<NodeInputType, NodeOutput<NodeOutputType>, NodeErrorType, _>
  • Input: Into<NodeInputType>,
  • NodeErrorType: Into<Error>,
§Returns

A new Builder with the added node.

where Input: Send, Error: Send, Context: Send,

Source

pub fn add_node<NodeType, NodeInput, NodeOutput, NodeError>( self, node: NodeType, ) -> Builder<Input, Output, Error, Context, (NodeTypes, NodeType), ((OtherNodeIOETypes, (LastNodeInType, NodeOutput<LastNodeOutType>, LastNodeErrType)), (NodeInput, NodeOutput<NodeOutput>, NodeError))>
where LastNodeOutType: Into<NodeInput>, NodeError: Into<Error>, NodeType: Node<NodeInput, NodeOutputStruct<NodeOutput>, NodeError, Context> + Clone + Send + Sync, NodeInput: Send,

Adds a new node.

The new node must satisfy:

  • Self: Node<NodeInputType, NodeOutput<NodeOutputType>, NodeErrorType, _>
  • NodeErrorType: Into<Error>,
  • LastNodeOutputType: Into<NodeInputType>,
§Returns

A new Builder with the added node.

Source

pub fn build( self, ) -> Flow<Input, Output, Error, Context, NodeTypes, (OtherNodeIOETypes, (LastNodeInType, NodeOutput<LastNodeOutType>, LastNodeErrType))>
where LastNodeOutType: Into<Output>,

Finalizes the builder and produces a SequentialFlow instance.
