Struct everscale_types::cell::builder::CellBuilder

pub struct CellBuilder<C: CellFamily> { /* private fields */ }

Builder for constructing cells with densely packed data.

Implementations

impl<C: CellFamily> CellBuilder<C>

pub fn new() -> Self

Creates an empty cell builder.

impl<C: CellFamily> CellBuilder<C>where
    CellContainer<C>: AsRef<dyn Cell<C>>,

pub fn compute_level(&self) -> u8

Computes the cell level from the level mask.

pub fn compute_level_mask(&self) -> LevelMask

pub fn bit_len(&self) -> u16

Returns the data size of this cell in bits.

pub fn spare_bits_capacity(&self) -> u16

Returns remaining data capacity in bits.

pub fn spare_refs_capacity(&self) -> u8

Returns remaining references capacity.

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

Explicitly sets the level mask and marks this cell as exotic.

pub fn set_level_mask(&mut self, level_mask: LevelMask)

Explicitly sets the level mask and marks this cell as exotic.

pub fn store_zeros(&mut self, bits: u16) -> bool

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

pub fn store_bit_zero(&mut self) -> bool

Tries to store one zero bit in the cell, returning false if there is not enough remaining capacity.

pub fn store_bit_true(&mut self) -> bool

Tries to store one non-zero bit in the cell, returning false if there is not enough remaining capacity.

pub fn store_u8(&mut self, value: u8) -> bool

Tries to store u8 in the cell, returning false if there is not enough remaining capacity.

pub fn store_u16(&mut self, value: u16) -> bool

Tries to store u16 in the cell, returning false if there is not enough remaining capacity.

pub fn store_u32(&mut self, value: u32) -> bool

Tries to store u32 in the cell, returning false if there is not enough remaining capacity.

pub fn store_u64(&mut self, value: u64) -> bool

Tries to store u64 in the cell, returning false if there is not enough remaining capacity.

pub fn store_u128(&mut self, value: u128) -> bool

Tries to store u128 in the cell, returning false if there is not enough remaining capacity.

pub fn store_u256(&mut self, value: &[u8; 32]) -> bool

Tries to store 32 bytes in the cell, returning false if there is not enough remaining capacity.

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

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) -> bool

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 references(&self) -> &[CellContainer<C>]

Returns a slice of the child cells stored in the builder.

pub fn store_reference(&mut self, cell: CellContainer<C>) -> bool

Tries to store a child in the cell, returning false if there is not enough remaining capacity.

pub fn build(self) -> Option<CellContainer<C>>

Tries to build a new cell using the default finalizer.

See Finalizer

pub fn build_ext(
    self,
    finalizer: &mut dyn Finalizer<C>
) -> Option<CellContainer<C>>

Tries to build a new cell using the specified finalizer.

Trait Implementations

impl<C: CellFamily> Default for CellBuilder<C>

fn default() -> Self

Returns the “default value” for a type.
