Methods

impl StorageValueConfigProposeData

fn new(
    tx_propose: TxConfigPropose,
    votes_history_hash: &Hash,
    num_votes: u64
) -> StorageValueConfigProposeData

Creates a new instance with given parameters.

fn hash(&self) -> Hash

Hashes data as a raw byte array and returns the resulting hash.

fn tx_propose(&self) -> TxConfigPropose

fn votes_history_hash(&self) -> &Hash

fn num_votes(&self) -> u64

impl StorageValueConfigProposeData

This structure logically contains 2 fields:

1. TxConfigPropose in tx_propose field.

2. Reference to votes_by_config_hash table. This reference is represented by 2 fields:

   • votest_history_hash
   • num_votes

Length of the table is stored in num_votes field, which isn't changed after table initialization, because number of possible vote slots for a config is determined by number of validators in its previous config.

Table's root hash - in votes_history_hash field, which is modified after a vote from validator is added.

fn set_history_hash(&mut self, hash: &Hash)

Method to mutate votes_history_hash field containing root hash of votes_by_config_hash after replacing empty vote with a real TxConfigVote cast by a validator.

Trait Implementations

impl Clone for StorageValueConfigProposeData

fn clone(&self) -> StorageValueConfigProposeData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for StorageValueConfigProposeData

fn eq(&self, __arg_0: &StorageValueConfigProposeData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &StorageValueConfigProposeData) -> bool

This method tests for !=.

impl<'a> Field<'a> for StorageValueConfigProposeData

unsafe fn read(buffer: &'a [u8], from: Offset, to: Offset) -> Self

Read Field from buffer, with given position, beware of memory unsafety, you should check Field before read.

fn write(&self, buffer: &mut Vec<u8>, from: Offset, to: Offset)

Write Field to buffer, in given position write doesn't lead to memory unsafety.

fn check(
    buffer: &'a [u8],
    from_st_val: CheckedOffset,
    to_st_val: CheckedOffset,
    latest_segment: CheckedOffset
) -> Result

Checks if data in the buffer could be deserialized. Returns an index of latest data seen.

fn field_size() -> Offset

Field's header size

impl StorageValue for StorageValueConfigProposeData

fn into_bytes(self) -> Vec<u8>

Serialize a value into a vector of bytes.

fn from_bytes(v: Cow<[u8]>) -> Self

Deserialize a value from bytes.

fn hash(&self) -> Hash

Returns a hash of the value.

impl Debug for StorageValueConfigProposeData

fn fmt(&self, fmt: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl ExonumJson for StorageValueConfigProposeData
