Struct MetadataReloadHandle 

pub struct MetadataReloadHandle { /* private fields */ }

The engine half of the deployment admin POST /admin/reload-metadata (memra#76): re-read the boot MEMRA_MODEL_METADATA file, validate it with the boot checks, and atomically swap it for new requests. A failed reload keeps the old set — validation runs BEFORE the swap, never on it.

In-flight requests are unaffected by construction: handlers resolve their metadata from an Arc cloned at admission, so they keep the set they started with. Weights, kernel-shaping flags, and the MEMRA_MODELS roster are out of scope and untouched: an alias the boot roster does not name is rejected exactly like at boot.

Memory-only: unlike the worker-command handles this one needs no drop on the shutdown signal.

Default is the unwired state (empty set, empty roster, no path): a reload on it fails closed, which is what deployment-surface tests assert the pre-ready route with — beyond that, surfaces receive the wired handle from on_ready.

Implementations

impl MetadataReloadHandle

pub fn reload(&self) -> Result<MetadataReloadReceipt, String>

impl Clone for MetadataReloadHandle

fn clone(&self) -> MetadataReloadHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.
