Struct VoteStateHandler 

pub struct VoteStateHandler { /* private fields */ }

Vote state handler for

• Deserializing vote state
• Converting vote state in-memory to target version
• Operating on the vote state data agnostically
• Serializing the resulting state to the vote account

pub fn init_vote_account_state_v2( vote_account: &mut BorrowedInstructionAccount<'_, '_>, vote_init: &VoteInitV2, inflation_rewards_collector: &Pubkey, block_revenue_collector: &Pubkey, clock: &Clock, target_version: VoteStateTargetVersion, ) -> Result<(), InstructionError>

pub fn deinitialize_vote_account_state( vote_account: &mut BorrowedInstructionAccount<'_, '_>, target_version: VoteStateTargetVersion, ) -> Result<(), InstructionError>

pub fn check_vote_account_length( vote_account: &mut BorrowedInstructionAccount<'_, '_>, target_version: VoteStateTargetVersion, ) -> Result<(), InstructionError>

pub fn increment_credits(&mut self, epoch: Epoch, credits: u64)

pub fn process_next_vote_slot( &mut self, next_vote_slot: Slot, epoch: Epoch, current_slot: Slot, )

pub fn new_v4(vote_state: VoteStateV4) -> Self

pub fn try_new_from_vote_state_versions( versions: VoteStateVersions, ) -> Result<Self, InstructionError>

Constructs a VoteStateHandler of the same version as the input VoteStateVersions.

Returns Err(InstructionError::InvalidAccountData) if the version of the input VoteStateVersions is not supported by VoteStateHandler.

pub fn default_v4() -> Self

pub fn as_ref_v4(&self) -> &VoteStateV4

pub fn unwrap_v4(self) -> VoteStateV4

pub fn serialize_into(self, data: &mut [u8]) -> Result<(), InstructionError>

Serializes self into the provided data buffer.

Returns Err(InstructionError::InvalidAccountData) if serialization fails.

Trait Implementations

impl Clone for VoteStateHandler

fn clone(&self) -> VoteStateHandler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VoteStateHandler

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

Formats the value using the given formatter.

impl PartialEq for VoteStateHandler

fn eq(&self, other: &VoteStateHandler) -> 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.
