Struct Builder 

pub struct Builder<Input, Output, Error, Context, NodeTypes = (), NodeIOETypes = ()>
where
    Input: Send + Clone,
    Context: Fork + Update + Send,
{ /* private fields */ }

Builder for OneOfSequentialFlow.

This builder ensures:

• Input into the flow can be converted into the input of all nodes
• output of all nodes can be converted into the Output of the flow
• error of all nodes can be converted into the Error of the flow

See also OneOfSequentialFlow.

Implementations

impl<Input, Output, Error, Context> Builder<Input, Output, Error, Context>

where Input: Send + Clone, Context: Fork + Update + Send,

pub fn new() -> Self

Creates a new empty builder for OneOfSequentialFlow.

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>, NodeOutput: Into<Output>, NodeError: Into<Error>, NodeType: Node<NodeInput, NodeOutput<NodeOutput>, NodeError, Context> + Send + Sync + Clone,

Adds a new node.

The new node must satisfy:

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

Returns

A new Builder with the added node.

impl<Input, Output, Error, Context, NodeTypes, LastNodeIOETypes, OtherNodeIOETypes> Builder<Input, Output, Error, Context, NodeTypes, (OtherNodeIOETypes, LastNodeIOETypes)>

where Input: Send + Clone, Context: Fork + Update + Send,

pub fn add_node<NodeType, NodeInput, NodeOutput, NodeError>( self, node: NodeType, ) -> Builder<Input, Output, Error, Context, (NodeTypes, NodeType), ((OtherNodeIOETypes, LastNodeIOETypes), (NodeInput, NodeOutput<NodeOutput>, NodeError))>

where Input: Into<NodeInput>, NodeOutput: Into<Output>, NodeError: Into<Error>, NodeType: Node<NodeInput, NodeOutput<NodeOutput>, NodeError, Context> + Send + Sync + Clone,

Adds a new node.

The new node must satisfy:

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

Returns

A new Builder with the added node.

pub fn build( self, ) -> OneOfSequentialFlow<Input, Output, Error, Context, NodeTypes, (OtherNodeIOETypes, LastNodeIOETypes)>

Finalizes the builder and produces a OneOfSequentialFlow instance.

Trait Implementations

impl<Input, Output, Error, Context, NodeTypes, NodeIOETypes> Debug for Builder<Input, Output, Error, Context, NodeTypes, NodeIOETypes>

where NodeTypes: ChainDebug, Input: Send + Clone, Context: Fork + Update + Send,

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

Formats the value using the given formatter.

impl<Input, Output, Error, Context> Default for Builder<Input, Output, Error, Context>

where Input: Send + Clone, Context: Fork + Update + Send,

fn default() -> Self

Returns the “default value” for a type.
