Enum Versions

pub enum Versions {
    Legacy(Box<State>),
    Current(Box<State>),
}

Variants

Legacy(Box<State>)

Current(Box<State>)

Current variants have durable nonce and blockhash domains separated.

Implementations

impl Versions

pub fn new(state: State) -> Versions

pub fn state(&self) -> &State

pub fn verify_recent_blockhash(&self, recent_blockhash: &Hash) -> Option<&Data>

Checks if the recent_blockhash field in Transaction verifies, and returns nonce account data if so.

pub fn upgrade(self) -> Option<Versions>

Upgrades legacy nonces out of chain blockhash domains.

pub fn authorize( self, signers: &HashSet<Pubkey>, authority: Pubkey, ) -> Result<Versions, AuthorizeNonceError>

Updates the authority pubkey on the nonce account.

Trait Implementations

impl Clone for Versions

fn clone(&self) -> Versions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Versions

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Versions

fn deserialize<__D>( __deserializer: __D, ) -> Result<Versions, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Versions> for State

fn from(versions: Versions) -> State

Converts to this type from the input type.

impl PartialEq for Versions

fn eq(&self, other: &Versions) -> 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 Versions

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Versions

impl StructuralPartialEq for Versions
