Struct MapNode 

pub struct MapNode<In, Out, F> { /* private fields */ }

Applies a mapping function to transform input to output.

Implementations

impl<In, Out, F> MapNode<In, Out, F>

where F: Fn(In) -> Out + Send + Sync + 'static,

pub fn new(f: F) -> Self

Trait Implementations

impl<In, Out, F> Clone for MapNode<In, Out, F>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<In, Out, F> Debug for MapNode<In, Out, F>

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

Formats the value using the given formatter.

impl<In, Out, F> Transition<In, Out> for MapNode<In, Out, F>

where In: Send + Sync + 'static, Out: Send + Sync + 'static, F: Fn(In) -> Out + Send + Sync + 'static,

type Error = String

Domain-specific error type (e.g., AuthError, ValidationError)

type Resources = ()

The type of resources required by this transition. This follows the “Hard-Wired Types” principle from the Master Plan.

fn run<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, input: In, _resources: &'life1 Self::Resources, _bus: &'life2 mut Bus, ) -> Pin<Box<dyn Future<Output = Outcome<Out, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute the transition.

fn label(&self) -> String

Execute the transition.

fn description(&self) -> Option<String>

Returns a detailed description of what this transition does.

fn position(&self) -> Option<(f32, f32)>

Returns the visual position of this transition in a schematic. (x, y) coordinates.

fn bus_access_policy(&self) -> Option<BusAccessPolicy>

Optional transition-scoped Bus access policy (M143).

fn input_schema(&self) -> Option<Value>

Optional JSON Schema for the input type of this transition.
