Expand description

Buffer manager interface for kernel-driver communication.

This trait defines how buffers are stored and retrieved. The kernel provides pure storage mechanisms, while drivers implement I/O operations.

§Design Philosophy

No I/O operations: No open()/save() methods - VFS driver handles these
No focus tracking: Active buffer tracking is a runtime/window concern
Thread-safe: Uses Arc<RwLock<Buffer>> for concurrent access
Kernel purity: Pure mechanisms only, no external dependencies

§Example

use reovim_kernel::api::v1::{BufferManager, Buffer, BufferId};

struct SimpleBufferManager { /* ... */ }

impl BufferManager for SimpleBufferManager {
    fn get(&self, id: BufferId) -> Option<Arc<RwLock<Buffer>>> {
        // Implementation
    }
    // ... other methods
}
