pub enum SingleOrVec<T> {
    Single(Box<T>),
    Vec(Vec<T>),
}
Expand description

A type which can be serialized as a single item, or multiple items.

In some contexts, a Single may be semantically distinct from a Vec containing only item.

Variants

Single(Box<T>)

Vec(Vec<T>)

Implementations

Returns true if self is either a Single equal to x, or a Vec containing x.

Examples
use schemars::schema::SingleOrVec;

let s = SingleOrVec::from(10);
assert!(s.contains(&10));
assert!(!s.contains(&20));

let v = SingleOrVec::from(vec![10, 20]);
assert!(v.contains(&10));
assert!(v.contains(&20));
assert!(!v.contains(&30));
