Enum SingleOrMultiple 

pub enum SingleOrMultiple {
    Single([String; 1]),
    Multiple(Vec<String>),
}

Represents a choice between a single value or multiple string values.

Examples

let single: SingleOrMultiple = "foobar".into();
let expected_json = r#""foobar""#;

let serialized = serde_json::to_string(&single).unwrap();
assert_eq!(expected_json, serialized);

let deserialized: SingleOrMultiple = serde_json::from_str(&serialized).unwrap();
assert_eq!(deserialized, single);

let multiple: SingleOrMultiple = ["foo", "bar", "baz"].as_slice().into();
let expected_json = r#"["foo","bar","baz"]"#;

let serialized = serde_json::to_string(&multiple).unwrap();
assert_eq!(expected_json, serialized);

let deserialized: SingleOrMultiple = serde_json::from_str(&serialized).unwrap();
assert_eq!(deserialized, multiple);

Variants

Single([String; 1])

One single value

Multiple(Vec<String>)

Multiple values
