Enum enso_prelude::at_least_one_of_two::AtLeastOneOfTwo[−][src]

pub enum AtLeastOneOfTwo<T1, T2> {
    First(T1),
    Second(T2),
    Both(T1, T2),
}
Expand description

A struct similar to Option and Either. It can contain the first value, or the second value, or both of them at the same time.

Variants

First(T1)
Second(T2)
Both(T1, T2)
