This is a pure-rust asynchronous network synchronization crate (using tokio) that recreates familiar asynchronous paradigms but in a network context.

Let A and B be two nodes with a pre-established ordered+reliable connection to each other (e.g., over TCP, TLS, QUIC, etc)

  • join Given A executing function f_a -> r_a and B executing function f_b -> r_b, return r_a to A and r_b to B
  • try_join Given A executing function f_a -> Result<r_a> and B executing function f_b -> Result<r_b>, return Result<r_a> to A and Result<r_b> to B iff Result<r_a> = Ok(r_a) AND Result<r_b> = Ok(r_b). A global error is returned if either one of the nodes fails
  • select Given A executing function f_a -> r_a and B executing function f_b -> r_b, return r_a to A if r_a is computed first, or, return r_b to B if r_b is computed first
  • try_select Given A executing function f_a -> Result<r_a> and B executing function f_b -> Result<r_b>, return Result<r_a> to A if Result<r_a> is computed first AND Result<r_a> = Ok(r_a), or, return Result<r_b> to B if Result<r_b> is computed first AND Result<r_b> = Ok(r_b). Returns a global error if both nodes fail.

NetMutex: A mutual exclusion algorithm for sharing memory in a synchronized mannor between two nodes NetRwLock: Allows a single writer or many readers between two nodes

Additionally, there is a sync_start file that allows the synchronization of two operations at approximately the same time. Examples for every operation are in the source code under src/sync/[...]
