# core::circuit::CircuitModulus

A type that can be used as a circuit modulus (a u384 that is not zero or one).
The modulus defines the finite field over which the circuit operates. It must be:

* A 384-bit number (represented as four 96-bit limbs)
* Not zero or one
* Typically a prime number for cryptographic applications

## Signature

```rust theme={null}
pub extern type CircuitModulus;
```
