//! It implements field variables for `crate::{Fq, Fq2, Fq6, Fq12}`,

//! This module implements the R1CS equivalent of `ark_mnt6_753`.
|
|||
//!
|
|||
//! It implements field variables for `crate::{Fq, Fq3, Fq6}`,
|
|||
//! group variables for `crate::{G1, G2}`, and implements constraint
|
|||
//! generation for computing `MNT6_753::pairing`.
|
|||
//!
|
|||
//! The field underlying these constraints is `crate::Fq`.
|
|||
//!
|
|||
//! # Examples
|
|||
//!
|
|||
//! One can perform standard algebraic operations on `FqVar`:

|

|

//! One can also perform standard algebraic operations on `G1Var` and `G2Var`:

|

|

//! Finally, one can check pairing computations as well:
