Struct ScriptRegistry 

pub struct ScriptRegistry { /* private fields */ }

In-memory script registry with optional link-time inventory discovery.

Populated at boot via Self::from_inventory / Self::register_from_inventory (from #[chronon::script]) or manual Self::register calls. Read by the executor when a run is claimed.

In Mode 2 (coordinator + worker), scripts must be registered on worker binaries — that is where handlers execute. Prefer ChrononBuilder::auto_registry() so inventory is collected automatically.

Examples

Empty registry:

use chronon_executor::ScriptRegistry;

let registry = ScriptRegistry::new();
assert!(registry.is_empty());

Explicit register (daemon-style, without the macro):

use chronon_core::{Result, ScriptContext};
use chronon_executor::{ScriptDescriptor, ScriptRegistry};

fn noop(
    _ctx: Box<dyn ScriptContext>,
    _params: serde_json::Value,
) -> std::pin::Pin<Box<dyn std::future::Future<Output = Result<()>> + Send>> {
    Box::pin(async { Ok(()) })
}

let mut registry = ScriptRegistry::new();
registry.register(ScriptDescriptor::new("daemon-noop", noop));
assert!(registry.contains("daemon-noop"));
assert_eq!(registry.len(), 1);

Implementations

impl ScriptRegistry

pub fn new() -> Self

Creates an empty registry with no registered scripts.

Examples

use chronon_executor::ScriptRegistry;

let registry = ScriptRegistry::new();
assert!(registry.is_empty());

pub fn from_inventory() -> Self

Populate from all #[chronon::script] descriptors linked into the binary.

Equivalent to ChrononBuilder::auto_registry() wiring. Prefer this on Mode 2 workers.

pub fn register_from_inventory(&mut self)

Register every script descriptor collected via link-time inventory.

pub fn register(&mut self, desc: ScriptDescriptor)

Inserts or replaces a script descriptor keyed by ScriptDescriptor::name.

Duplicate names overwrite the previous handler without error.

pub fn get(&self, name: &str) -> Option<ScriptDescriptorRef<'_>>

Returns a borrowed view of the script named name, if registered.

pub fn get_or_err(&self, name: &str) -> Result<ScriptDescriptorRef<'_>>

Like Self::get, but returns ChrononError::ScriptNotFound when absent.

pub fn len(&self) -> usize

Returns the number of registered scripts.

pub fn is_empty(&self) -> bool

Returns true when no scripts are registered.

pub fn contains(&self, name: &str) -> bool

Returns true when a script with the given name is registered.

pub fn list(&self) -> Vec<ScriptDescriptorRef<'_>>

Returns all registered scripts sorted by name.

Trait Implementations

impl Default for ScriptRegistry

fn default() -> Self

Returns the “default value” for a type.
