Fields

authority: Pubkey

The creator of the variable.

commit: [u8; 32]

The commit provided by Entropy provider.

seed: [u8; 32]

The revealed seed.

slot_hash: [u8; 32]

The slot hash

value: [u8; 32]

The current value of the variable.

samples: u64

The number of random variables remaining to be sampled.

is_auto: u64

Whether or not the Entropy provider should automatically sample the slot hash.

start_at: u64

The slot at which the variable was opened.

end_at: u64

The slot at which the variable should sample the slothash.

Trait Implementations

impl AccountValidation for Var

where F: Fn(&Self) -> bool,

fn assert_msg<F>(&self, condition: F, msg: &str) -> Result<&Self, ProgramError>

impl Clone for Var

fn clone(&self) -> Var

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Var

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

Formats the value using the given formatter.

impl Discriminator for Var

fn discriminator() -> u8

impl PartialEq for Var

fn eq(&self, other: &Var) -> 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 Zeroable for Var

fn zeroed() -> Self

Calls zeroed.

impl Copy for Var

impl Pod for Var

impl StructuralPartialEq for Var
