Crate mmap_sync

mmap-sync is a high-performance, concurrent data access library for Rust. It is designed to handle data access between a single writer process and multiple reader processes efficiently using memory-mapped files, wait-free synchronization, and zero-copy deserialization.

Features

• Memory-mapped files: This allows different processes to access the same memory space, bypassing the need for costly serialization and deserialization. As a result, mmap-sync provides fast, low-overhead data sharing between processes.

• Wait-free synchronization: Inspired by Linux kernel’s Read-Copy-Update (RCU) pattern and the Left-Right concurrency control technique. Write access to the data is managed by a single writer, with multiple readers able to access the data concurrently.

• Zero-copy deserialization: Leveraging the rkyv library, mmap-sync achieves efficient data storage and retrieval. The templated type T for Synchronizer can be any Rust struct implementing specified rkyv traits.

Modules

guard

The guard module manages read access to shared memory, utilizing RAII (Resource Acquisition Is Initialization) principles to control access lifecycle.

instance

locks

Lock strategies.

synchronizer

The synchronizer module is the core component of the mmap-sync library, providing a Synchronizer struct for concurrent data access.
