Enum solana_program::nonce::state::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, separate_domains: bool) -> Self

pub fn state(&self) -> &State

pub fn separate_domains(&self) -> bool

Returns true if the durable nonce is not in the blockhash domain.

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

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

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

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

Formats the value using the given formatter.

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

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

Deserialize this value from the given Serde deserializer.

impl From<Versions> for State

fn from(versions: Versions) -> Self

Converts to this type from the input type.

impl PartialEq<Versions> for Versions

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

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

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

This method 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::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
