Struct RuntimeConfigSnapshot 

pub struct RuntimeConfigSnapshot { /* private fields */ }

Immutable runtime configuration snapshot.

A snapshot is readable after later reconfiguration because the runtime publishes a new Arc instead of mutating existing slots.

Examples

use tenferro_runtime::RuntimeConfigBuilder;

let runtime = RuntimeConfigBuilder::new().build()?;
let snapshot = runtime.snapshot()?;
assert_eq!(snapshot.engine_count(), 0);
