Struct SkipUnknown 

pub struct SkipUnknown;

Unknown keys stepped over rather than refused.

The policy for reading a subset of a document you did not define, or one written against a newer version of your schema.

use structio::{ErrorCode, SkipUnknown, from_str, from_str_with};

let doc = r#"{"port":8080,"debug":true}"#;
assert_eq!(from_str::<Port>(doc).unwrap_err().code, ErrorCode::UnknownKey);
assert_eq!(from_str_with::<SkipUnknown, Port>(doc).unwrap().port, 8080);
