Implementations

impl PullFeedAccountData

pub fn discriminator() -> [u8; 8]

pub fn parse<'info>( data: Ref<'info, &mut [u8]>, ) -> Result<Ref<'info, Self>, OnDemandError>

pub fn generate_checksum(&self, result: i128, slothash: [u8; 32]) -> [u8; 32]

Generate a checksum for the given feed hash, result, slothash, max_variance and min_responses This is signed by the oracle and used to verify that the data submitted by the oracles is valid.

pub fn generate_checksum_inner( queue: Pubkey, feed_hash: [u8; 32], result: i128, slothash: [u8; 32], max_variance: u64, min_responses: u32, ) -> [u8; 32]

Generate a checksum for the given feed hash, result, slothash, max_variance and min_responses This is signed by the oracle and used to verify that the data submitted by the oracles is valid.

pub fn generate_checksum_with_timestamp( queue: Pubkey, feed_hash: [u8; 32], result: i128, slothash: [u8; 32], max_variance: u64, min_responses: u32, timestamp: u64, ) -> [u8; 32]

Generate a checksum for the given feed hash, result, slothash, max_variance and min_responses This is signed by the oracle and used to verify that the data submitted by the oracles is valid.

pub fn get_value( &self, clock: &Clock, max_staleness: u64, min_samples: u32, only_positive: bool, ) -> Result<Decimal, OnDemandError>

method get_value Returns the median value of the submissions in the last max_staleness slots. If there are fewer than min_samples submissions, returns an error. arguments

• clock - the clock to use for the current slot
• max_staleness - the maximum number of slots to consider
• min_samples - the minimum number of samples required to return a value returns
• Ok(Decimal) - the median value of the submissions in the last max_staleness slots

pub fn value(&self) -> Option<Decimal>

The median value of the submissions needed for quorom size

pub fn std_dev(&self) -> Option<Decimal>

The standard deviation of the submissions needed for quorom size

pub fn mean(&self) -> Option<Decimal>

The mean of the submissions needed for quorom size

pub fn range(&self) -> Option<Decimal>

The range of the submissions needed for quorom size

pub fn min_value(&self) -> Option<Decimal>

The minimum value of the submissions needed for quorom size

pub fn max_value(&self) -> Option<Decimal>

The maximum value of the submissions needed for quorom size
