Required Methods§

fn from_field(field: &Self::Field) -> Result<Self, Error>where Self: Sized,

Initializes an object from a base field element.

Implementations on Foreign Types§

§

impl<E, I> FromField for Integer<E, I>where E: Environment, I: IntegerType,

§

fn from_field( field: &<Integer<E, I> as FromField>::Field ) -> Result<Integer<E, I>, Error>

Casts an integer from a base field.

This method guarantees the following:

  1. If the field element is larger than the integer domain, then the operation will fail.
  2. If the field element is smaller than the integer domain, then the operation will succeed.

type Field = Field<E>
