Struct Cells 

pub struct Cells { /* private fields */ }

The fleet’s cell tables, scalar and text. Cheap to clone.

Implementations

impl Cells

pub fn new(fleet: Arc<Fleet>) -> Result<Self>

pub fn allocate_text(&self, initial: &str) -> Result<Text>

Take a text cell holding initial; up to CELL_TEXT_MAX bytes.

pub fn open_text(&self, id: TextId) -> Result<Text>

A handle to a live text cell.

pub fn release_text(&self, id: TextId) -> Result<()>

pub fn is_text_live(&self, id: TextId) -> bool

pub fn allocate<T: CellType>(&self, initial: T) -> Result<Orbital<T>>

Take a free slot, stamp it with T and initial, and return the handle. The id inside it is what other processes open.

pub fn open<T: CellType>(&self, id: CellId) -> Result<Orbital<T>>

A handle to a live cell of type T.

pub fn release(&self, id: CellId) -> Result<()>

Give the slot back. Every handle to this generation goes stale.

pub fn is_live(&self, id: CellId) -> bool

Whether id names a live cell right now.

pub fn reset_all(&self) -> Result<()>

Clear both tables during quiescent owner boot.

pub fn unlink(&self) -> Result<()>

Remove the cell SHM object. Existing mappings remain valid until their processes release them.

Trait Implementations

impl Clone for Cells

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
