Struct Cell 

pub struct Cell(/* private fields */);

Thread-safe cell.

Implementations

impl Cell

pub fn untrack(self) -> Self

Unwraps the root cell from the usage tracking.

pub fn downgrade(this: &Cell) -> WeakCell

Creates a new WeakCell reference to this cell.

Methods from Deref<Target = DynCell>

pub fn cell_type(&self) -> CellType

Computes cell type from descriptor bytes.

pub fn level(&self) -> u8

Computes the cell level from the level mask.

pub fn level_mask(&self) -> LevelMask

Computes the level mask from the descriptor bytes.

pub fn reference_count(&self) -> u8

Computes the number of child cells from descriptor bytes.

pub fn get_reference_as_slice(&self, index: u8) -> Result<CellSlice<'_>, Error>

Tries to load the specified child cell as slice. Returns an error if the loaded cell is absent or is pruned.

pub fn is_exotic(&self) -> bool

Returns whether the cell is not Ordinary.

pub fn repr_hash(&self) -> &HashBytes

Returns a representation hash of the cell.

pub fn repr_depth(&self) -> u16

Returns a representation depth of the cell.

pub fn is_empty(&self) -> bool

Returns true if the cell is empty (no bits, no refs).

pub fn references(&self) -> RefsIter<'_>

Creates an iterator through child nodes.

pub fn as_slice(&self) -> Result<CellSlice<'_>, Error>

Returns this cell as a cell slice. Returns an error if the cell is pruned.

pub unsafe fn as_slice_unchecked(&self) -> CellSlice<'_>

Returns this cell as a cell slice.

Safety

The following must be true:

• cell is not pruned

pub fn compute_unique_stats(&self, limit: usize) -> Option<CellTreeStats>

Recursively computes the count of distinct cells returning the total storage used by this dag taking into account the identification of equal cells.

pub fn debug_root(&self) -> DebugCell<'_>

Returns an object that implements Debug for printing only the root cell of the cell tree.

pub fn display_root(&self) -> DisplayCellRoot<'_>

Returns an object that implements Display for printing only the root cell of the cell tree.

pub fn display_tree(&self) -> DisplayCellTree<'_>

Returns an object that implements Display for printing all cells in the cell tree.

pub fn display_data(&self) -> impl Display + Binary + '_

Returns an object which will display cell data as a bitstring with a termination bit.

pub fn parse<'a, T: Load<'a>>(&'a self) -> Result<T, Error>

Converts this cell into a slice and tries to load the specified type from it.

NOTE: parsing Cell will load the first reference!

impl<T: CellImpl + Send + Sync + 'static> From<Arc<T>> for Cell

fn from(value: CellInner<T>) -> Self

Converts to this type from the input type.

impl From<Arc<dyn CellImpl + Send + Sync>> for Cell

fn from(value: CellInner) -> Self

Converts to this type from the input type.

impl From<Cell> for CellInner

fn from(value: Cell) -> Self

Converts to this type from the input type.

impl FromAbi for Cell

fn from_abi(value: AbiValue) -> Result<Self>

Constructs self from the ABI value.

impl IntoAbi for Cell
