//! Netapp is a Rust library that takes care of a few common tasks in distributed software:
|
||||||
|
//!
|
||||||
|
//! - establishing secure connections
|
||||||
|
//! - managing connection lifetime, reconnecting on failure
|
||||||
|
//! - checking peer's state
|
||||||
|
//! - peer discovery
|
||||||
|
//! - query/response message passing model for communications
|
||||||
|
//! - multiplexing transfers over a connection
|
||||||
|
//! - overlay networks: full mesh, and soon other methods
|
||||||
|
//!
|
||||||
|
//! Of particular interest, read the documentation for the `netapp::NetApp` type,
|
||||||
|
//! the `message::Message` trait, and `proto::RequestPriority` to learn more
|
||||||
|
//! about message priorization.
|
||||||
|
//! Also check out the examples to learn how to use this crate.
