Implementations

impl Layout

pub fn create(dir: &Path, spec: GroupLayout) -> Result<Self>

pub fn open(dir: &Path, spec: GroupLayout) -> Result<Self>

Open an existing layout (panics if a file is missing or undersized).

pub fn fd(&self, layer: u32) -> RawFd

Raw fd for the io_uring / cuFile paths, which are Linux-only.

pub fn file(&self, layer: u32) -> &File

The layer file itself — what the portable positional-I/O backend uses, and the only accessor available on Windows.

pub fn offset(&self, key: GroupKey) -> u64

pub fn group_bytes(&self) -> u64
