Struct ComponentHandle 

pub struct ComponentHandle {
    pub type_name: &'static str,
    pub package: ComponentPackage,
    pub instance_id: u32,
    pub serialize_fn: fn(&(dyn ErasedComponent + 'static)) -> Vec<u8>,
    pub restore_fn: fn(&[u8]) -> Result<Box<dyn ErasedComponent>, RestoreError>,
    pub state_bytes: Vec<u8>,
}

Owned wrapper that travels through the ModelProto → Node pipeline. Carries captured fn pointers + state bytes.

Fields

type_name: &'static str

Stable type identifier.

package: ComponentPackage

Origin tag.

instance_id: u32

Per-Node instance disambiguator assigned by install.

serialize_fn: fn(&(dyn ErasedComponent + 'static)) -> Vec<u8>

Monomorphized T::serialize via downcast.

restore_fn: fn(&[u8]) -> Result<Box<dyn ErasedComponent>, RestoreError>

Monomorphized T::restore.

state_bytes: Vec<u8>

Serialized state captured at build or snapshot time.

Implementations

impl ComponentHandle

pub fn materialize(&self) -> Result<Box<dyn ErasedComponent>, RestoreError>

Materialize a fresh instance via restore_fn(state_bytes).

pub fn capture_state( &self, instance: &(dyn ErasedComponent + 'static), ) -> Vec<u8>

Capture state from a live &dyn ErasedComponent.

pub fn from_concrete<T>(instance: &T, instance_id: u32) -> ComponentHandle

where T: ConcreteComponent,

Build from a live &T: ConcreteComponent. Captures monomorphized serialize/restore + freezes current bytes.

Trait Implementations

impl Debug for ComponentHandle

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

Formats the value using the given formatter.
