format!(format, ..) works just like println! but returns the result as a string. • dbg!(expression) logs the value of the expression and returns it. 37 • todo!() marks a bit of code as not-yet-implemented a production build it would send messages to a log server. However, the StdoutLogger given below logs all messages, regardless of verbosity. Your task is to write a VerbosityFilter type that will ignore log to logcat (on-device) or stdout (on-host): hello_rust_logs/Android.bp: rust_binary { name: "hello_rust_logs", crate_name: "hello_rust_logs", srcs: ["src/main.rs"], rustlibs: [ "liblog_rust", "liblogger"

companies must balance EV charger loads and manage grid performance in real time. Banks need to analyze audit logs from their website and application in real time to understand customer behavior and spot potential integration bottlenecks. By bridging the gap between data producers (databases, applications, IoT devices, logs, etc.) and data consumers (dashboards, AI/ML models, analytics engines, business applications), a includes: Real-time data ingestion from structured, semi-structured and unstructured sources (IoT, logs, event streams).
