Struct Oracle 

#[repr(C)]
pub struct Oracle {
    pub idx: u64,
    pub active_size: u64,
    pub length: u64,
}

Fields

idx: u64

Index of latest observation slot

active_size: u64

Size of active sample. Active sample is initialized observation.

length: u64

Number of observations

Implementations

impl Oracle

pub fn init(&mut self)

pub fn increase_length(&mut self, length_to_increase: u64) -> Result<()>

pub fn space(observation_length: u64) -> usize

pub fn new_space( length_to_add: u64, account_loader: &AccountLoader<'_, Oracle>, ) -> Result<usize>

pub fn metadata_len() -> usize

Trait Implementations

impl AccountDeserialize for Oracle

fn try_deserialize(buf: &mut &[u8]) -> Result<Self>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl Clone for Oracle

fn clone(&self) -> Oracle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Oracle

impl Debug for Oracle

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

Formats the value using the given formatter.

impl Default for Oracle

fn default() -> Oracle

Returns the “default value” for a type.

impl Discriminator for Oracle

const DISCRIMINATOR: [u8; 8]

fn discriminator() -> [u8; 8]

impl Owner for Oracle

fn owner() -> Pubkey

impl Pod for Oracle

impl ZeroCopy for Oracle

impl Zeroable for Oracle

fn zeroed() -> Self

Calls zeroed.
