Struct Each 

pub struct Each<V>(/* private fields */);

Validates every item of a collection with V.

The violation of the first invalid item is reported with its index as parameter index, its code is the code of the violation of the item. For an Option the value is validated if there is one.

use deser_validate::{Each, Email, Validator};

let emails = vec!["jane@example.com".to_string(), "nope".to_string()];
let violation = Each::<Email>::validate(&emails).unwrap_err();
assert_eq!(violation.message(), "item 1: must be an email address");
assert!(Each::<Email>::validate(&None::<String>).is_ok());
