Struct MerkleUpdate 

pub struct MerkleUpdate {
    pub old_hash: HashBytes,
    pub new_hash: HashBytes,
    pub old_depth: u16,
    pub new_depth: u16,
    pub old: Cell,
    pub new: Cell,
}

Parsed Merkle update representation.

NOTE: Serialized into MerkleUpdate cell.

Fields

old_hash: HashBytes

Representation hash of the original cell.

new_hash: HashBytes

Representation hash of the updated cell.

old_depth: u16

Representation depth of the original cell.

new_depth: u16

Representation depth of the updated cell.

old: Cell

Partially pruned tree with unchanged cells of the origin cell.

new: Cell

Partially pruned tree with all cells that are not in the original cell.

Implementations

impl MerkleUpdate

pub const BITS: u16 = 552u16

The number of data bits that the Merkle update occupies.

pub const REFS: u8 = 2u8

The number of references that the Merkle update occupies.

pub fn create<'a, F>( old: &'a DynCell, new: &'a DynCell, f: F, ) -> MerkleUpdateBuilder<'a, F>

where F: MerkleFilter + 'a,

Starts building a Merkle update between the specified cells, using old cells determined by filter.

pub fn apply(&self, old: &Cell) -> Result<Cell, Error>

Tries to apply this Merkle update to the specified cell, producing a new cell and using an empty cell context.

pub fn apply_ext( &self, old: &Cell, context: &mut dyn CellContext, ) -> Result<Cell, Error>

Tries to apply this Merkle update to the specified cell, producing a new cell and using an empty cell context.

pub fn compute_removed_cells<'a>( &self, old: &'a DynCell, ) -> Result<HashMap<&'a HashBytes, u32>, Error>

Computes the removed cells diff using the original cell.

Trait Implementations

impl Clone for MerkleUpdate

fn clone(&self) -> MerkleUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleUpdate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MerkleUpdate

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MerkleUpdate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Load<'_> for MerkleUpdate

fn load_from(s: &mut CellSlice<'_>) -> Result<Self, Error>

Tries to load itself from a cell slice.

impl PartialEq for MerkleUpdate

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MerkleUpdate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Store for MerkleUpdate

fn store_into( &self, b: &mut CellBuilder, _: &mut dyn CellContext, ) -> Result<(), Error>

Tries to store itself into the cell builder.
