pub struct VecSkipError<T>(_);
Expand description

Deserialize a sequence into Vec<T>, skipping elements which fail to deserialize.

The serialization behavior is identical to Vec<T>. This is an alternative to Vec<T> which is resilient against unexpected data.

Examples

#[derive(Deserialize, Serialize)]
enum Color {
    Red,
    Green,
    Blue,
}
#[serde_as]
#[derive(Deserialize, Serialize)]
struct Palette(#[serde_as(as = "VecSkipError<_>")] Vec<Color>);

let data = Palette(vec![Blue, Green,]);
let source_json = r#"["Blue", "Yellow", "Green"]"#;
let data_json = r#"["Blue","Green"]"#;
// Ensure serialization and deserialization produce the expected results
assert_eq!(data_json, serde_json::to_string(&data).unwrap());
assert_eq!(data, serde_json::from_str(source_json).unwrap());
