Struct Case 

pub struct Case {
    pub condition: Arc<dyn Fn(&Value) -> Pin<Box<dyn Future<Output = bool> + Send>> + Send + Sync>,
    pub target: String,
    pub label: Option<String>,
}

A switch/case branch: if condition matches, route to target.

Fields

condition: Arc<dyn Fn(&Value) -> Pin<Box<dyn Future<Output = bool> + Send>> + Send + Sync>

target: String

label: Option<String>

Optional human-readable label used in visualization.

Implementations

impl Case

pub fn new( condition: impl Fn(&Value) -> bool + Send + Sync + 'static, target: impl Into<String>, ) -> Case

A case routing to target when the synchronous condition holds.

pub fn new_async<F, Fut>(condition: F, target: impl Into<String>) -> Case

where F: Fn(&Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = bool> + Send + 'static,

A case routing to target when the async condition holds.

pub fn labeled( condition: impl Fn(&Value) -> bool + Send + Sync + 'static, target: impl Into<String>, label: impl Into<String>, ) -> Case

A case with an explicit visualization label.

pub fn labeled_async<F, Fut>( condition: F, target: impl Into<String>, label: impl Into<String>, ) -> Case

where F: Fn(&Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = bool> + Send + 'static,

An async case with an explicit visualization label.
