Struct IoUringGridManager 

pub struct IoUringGridManager { /* private fields */ }

Linux io_uring-based zero-copy streamer.

Uses O_DIRECT to bypass the kernel page cache and achieve deterministic DMA transfers from NVMe to RAM.

Implementations

impl IoUringGridManager

pub fn new(file_path: &Path) -> Result<Self, IoError>

Creates a new io_uring grid manager.

Opens the file with O_DIRECT, creates an io_uring instance, and pins both buffers in physical RAM.

Trait Implementations

impl Drop for IoUringGridManager

Available on Linux only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ZeroCopyStreamer for IoUringGridManager

Available on Linux only.

fn async_read_chunk(&mut self, offset: u64) -> Result<(), IoError>

Issues an asynchronous hardware read into the INACTIVE buffer.

fn poll_completion(&mut self) -> Option<&[u8]>

Non-blocking poll for completion.

fn get_active_buffer(&self) -> &[u8]

Returns the currently active buffer for SIMD chunking.

fn buffer_size(&self) -> usize

Returns the buffer size in bytes.
