spring-rs is a microservice framework written in Rust, similar to SpringBoot in java. spring-rs provides an easily extensible plug-in system for integrating excellent projects in the Rust community, such as axum, sqlx, sea-orm, etc.
Compared with SpringBoot in java, spring-rs has higher performance and lower memory usage, allowing you to completely get rid of the bloated JVM and travel light.
