Struct Meta 

#[repr(C)]
pub struct Meta {
    pub rent_exempt_reserve: u64,
    pub authorized: Authorized,
    pub lockup: Lockup,
}

Fields

rent_exempt_reserve: u64

👎Deprecated since 3.0.1:

Stake account rent must be calculated via the Rent sysvar. This value will cease to be correct once lamports-per-byte is adjusted.

authorized: Authorized

lockup: Lockup

Implementations

impl Meta

pub fn set_lockup( &mut self, lockup: &LockupArgs, signers: &HashSet<Pubkey>, clock: &Clock, ) -> Result<(), InstructionError>

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> Meta

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> Iter<Self, R, T>

where R: Rng, Self: Sized,
