//! Shared I/O primitives for RustFS.
|
|
//!
|
|
//! This crate holds the buffer pool and the concurrency-control primitives
|
|
//! that the storage layer builds on:
|
|
//!
|
|
//! - Tiered `BytesPool` for buffer management
|
|
//! - Storage-media and access-pattern profiling (`io_profile`)
|
|
//! - Scheduler and priority-queue configuration shapes
|
|
//! - Backpressure admission, deadlock detection, lock optimization
|
|
//! - Progress tracking for long-running operations
|
|
//!
|
|
//! # Example
|
|
//!
|
|
//! ```ignore
|
|
//! use rustfs_io_core::BytesPool;
|
|
//!
|
|
//! let pool = BytesPool::new_tiered();
|
|
//! let mut buffer = pool.acquire_buffer(8192).await;
|
|
//! ```
