A loaded encrypted value ready for FHE computation. 
use privora_sdk_program::prelude::*;

let a: Encrypted<u8> = a_ref.load()?;
let b: Encrypted<u8> = b_ref.load()?;
let sum = a.add(&b)?;

​
Type Parameters

  • T: EncryptedInt - The encrypted integer type (u8, u32, or u64)

​
Arithmetic Methods

​
add

pub fn add(&self, other: &Self) -> Result<Self, ProgramError>
Add two encrypted values.

​
sub

pub fn sub(&self, other: &Self) -> Result<Self, ProgramError>
Subtract other from self.

​
mul

pub fn mul(&self, other: &Self) -> Result<Self, ProgramError>
Multiply two encrypted values.

​
Comparison Methods

​
ge

pub fn ge(&self, other: &Self) -> Result<EncryptedBool, ProgramError>
Check if self >= other.

​
gt

pub fn gt(&self, other: &Self) -> Result<EncryptedBool, ProgramError>
Check if self > other.

​
le

pub fn le(&self, other: &Self) -> Result<EncryptedBool, ProgramError>
Check if self <= other.

​
lt

pub fn lt(&self, other: &Self) -> Result<EncryptedBool, ProgramError>
Check if self < other.

​
eq_enc

pub fn eq_enc(&self, other: &Self) -> Result<EncryptedBool, ProgramError>
Check if self == other.

​
Min/Max Methods

​
min

pub fn min(&self, other: &Self) -> Result<Self, ProgramError>
Return the minimum of two values.

​
max

pub fn max(&self, other: &Self) -> Result<Self, ProgramError>
Return the maximum of two values.

​
Storage Methods

​
store

pub fn store(self) -> Result<EncryptedRef<T>, ProgramError>
Store the value and return a hash reference.

​
Utility Methods

​
from_raw

pub fn from_raw(data: Vec<u8>) -> Self
Create from raw ciphertext bytes.

​
as_bytes

pub fn as_bytes(&self) -> &[u8]
Get the ciphertext bytes.

​
into_bytes

pub fn into_bytes(self) -> Vec<u8>
Consume and return the ciphertext bytes.

​
Operator Overloads

// Using references
let sum = &a + &b;
let diff = &a - &b;
let prod = &a * &b;

​
Example

let buy_price = buy_price_ref.load()?;
let sell_price = sell_price_ref.load()?;
let buy_qty = buy_qty_ref.load()?;
let sell_qty = sell_qty_ref.load()?;

let can_match: EncryptedBool = buy_price.ge(&sell_price)?;
let fill_qty: Encrypted<u8> = buy_qty.min(&sell_qty)?;
let fill_qty_ref = fill_qty.store()?;
