Loader

Struct Loader 

Source
pub struct Loader<I, O>
where I: Send + 'static, O: Send + 'static,
{ /* private fields */ }
Expand description

Reconstructs runnables from definitions. Caller registers factories by name for each Lambda / Opaque kind they expect to load.

Implementations§

Source§

impl<I, O> Loader<I, O>
where I: Send + 'static, O: Send + 'static,

Source

pub fn new() -> Self

Empty loader.

Source

pub fn register<F>(&mut self, name: impl Into<String>, factory: F)
where F: Fn(&Value) -> Arc<dyn Runnable<I, O>> + Send + Sync + 'static,

Register a factory for a named lambda or opaque kind. The factory receives the params payload (serde_json::Value::Null for lambdas) and must produce an Arc<dyn Runnable<I, O>>.

Source

pub fn load(&self, def: &RunnableDefinition) -> Result<Arc<dyn Runnable<I, O>>>

Reconstruct a Runnable<I, O> from its definition.
