Implementations

impl TotalSolCache

pub fn new(current_update_epoch: u64) -> TotalSolCache

pub fn increment( &mut self, sol_in: UFix64<N9>, current_epoch: u64, ) -> Result<(), CoreError>

Adds lamports to the cached amount.

pub fn decrement( &mut self, sol_out: UFix64<N9>, current_epoch: u64, ) -> Result<(), CoreError>

Subtracts lamports from the cached amount.

pub fn set( &mut self, total_sol: UFix64<N9>, current_epoch: u64, ) -> Result<(), CoreError>

Resets cache and current epoch. Used only in price update instruction.

pub fn get_validated(&self, current_epoch: u64) -> Result<UFix64<N9>, CoreError>

Gets the total SOL cached value, if last update epoch is same as current.
