Implementations

impl CellBuilder

pub fn build_from<T>(data: T) -> Result<Cell, Error>where T: Store,

Builds a new cell from the specified data using the default finalizer.

pub fn build_from_ext<T>( data: T, finalizer: &mut dyn Finalizer ) -> Result<Cell, Error>where T: Store,

pub fn spare_refs_capacity(&self) -> u8

Returns remaining references capacity.

pub fn has_capacity(&self, bits: u16, refs: u8) -> bool

Returns true if there is enough remaining capacity to fit bits and refs.

pub fn with_level_mask(self, level_mask: LevelMask) -> Self

pub fn store_small_uint(&mut self, value: u8, bits: u16) -> Result<(), Error>

Tries to store u8 in the cell (but only the specified number of bits), returning false if there is not enough remaining capacity.

NOTE: if bits is greater than 8, pads the value with zeros (as high bits).

pub fn store_uint(&mut self, value: u64, bits: u16) -> Result<(), Error>

Tries to store u64 in the cell (but only the specified number of bits), returning false if there is not enough remaining capacity.

NOTE: if bits is greater than 64, pads the value with zeros (as high bits).

pub fn store_raw(&mut self, value: &[u8], bits: u16) -> Result<(), Error>

Tries to store bytes in the cell (but only the specified number of bits), returning false if there is not enough remaining capacity.

NOTE: if bits is greater than bytes * 8, pads the value with zeros (as high bits).

pub fn store_cell_data<T>(&mut self, value: T) -> Result<(), Error>where T: Borrow<DynCell>,

Tries to store all data bits of the specified cell in the current cell, returning false if there is not enough remaining capacity.

pub fn store_slice_data<'a, T>(&mut self, value: T) -> Result<(), Error>where T: Borrow<CellSlice<'a>>,
