AtomicNodeRole

allsource_core::infrastructure::web::api_v1

Struct AtomicNodeRole 

Source 
pub struct AtomicNodeRole(/* private fields */);
Expand description

Thread-safe, runtime-mutable node role for failover support.

Wraps an AtomicU8 so the read-only middleware and health endpoint always see the current role, even after a sentinel-triggered promotion.
