Struct exonum_configuration::ProposeData

pub struct ProposeData { /* fields omitted */ }

Extended information about a proposal used for the storage.

Methods

impl ProposeData

pub fn new(
    tx_propose: Propose,
    votes_history_hash: &Hash,
    num_validators: u64
) -> ProposeData

Creates a new instance with given parameters.

pub fn tx_propose(&self) -> Propose

Proposal transaction.

pub fn votes_history_hash(&self) -> &Hash

Merkle root of all votes for the proposal.

pub fn num_validators(&self) -> u64

Number of eligible voting validators.

impl ProposeData

pub fn set_history_hash(self, hash: &Hash) -> Self

Changes the votes_history_hash field of this structure, leaving other fields intact.

Trait Implementations

impl Clone for ProposeData

fn clone(&self) -> ProposeData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for ProposeData

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

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

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

This method tests for !=.

impl<'a> Field<'a> for ProposeData

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 CryptoHash for ProposeData

fn hash(&self) -> Hash

Returns a hash of the value.

impl StorageValue for ProposeData

Important traits for Vec<u8>

impl Write for Vec<u8>

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.

impl Debug for ProposeData

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

Formats the value using the given formatter.

impl ExonumJson for ProposeData

fn deserialize_field<B>(
    value: &Value,
    buffer: &mut B,
    from: Offset,
    to: Offset
) -> Result<(), Box<Error>> where
