Struct isotope::ctx::subst::Shift[][src]

pub struct Shift<T> {
    pub shift: i32,
    pub base: u32,
    // some fields omitted
}
Expand description

Shift a term up or down by an amount

Fields

shift: i32

The amount to shift variables by

base: u32

The base of this context: leaves variables under this untouched (but not necessarily their annotations!)

Implementations

Create a new shift
