Crate reovim_kernel 

Core kernel mechanisms for reovim.

Linux equivalent: kernel/

This crate provides pure mechanisms without I/O. Drivers and modules implement policies using these primitives.

Usage

All public APIs are accessed via the api::v1 module:

use reovim_kernel::api::v1::*;

// Check API compatibility
check_api_version(Version::new(1, 0, 0))?;

// Use kernel types
let bus = EventBus::new();
pr_info!("kernel initialized");

Subsystems

Internal subsystems (not directly accessible):

• sched: Scheduler and runtime (Linux: kernel/sched/)
• mm: Memory management / buffers (Linux: mm/)
• ipc: Inter-process communication / events (Linux: ipc/)
• core: Core primitives (motion, text objects, commands)
• block: Block operations (undo, transactions)
• printk: Kernel logging (Linux: kernel/printk/)
• debug: Tracing and metrics
• panic: Panic handling and recovery

All subsystem types are re-exported through api::v1.
