Deserialize a map` and skip all elements failing to deserialize by @johnmave126 (#763)
MapSkipError
acts like a map (HashMap
/BTreeMap
), but keys or values that fail to deserialize, like are ignored.For formats with heterogeneously typed maps, we can collect only the elements where both key and value are deserializable. This is also useful in conjunction to
#[serde(flatten)]
to ignore some entries when capturing additional fields.// JSON "value": {"0": "v0", "5": "v5", "str": "str", "10": 2}, // Rust #[serde_as(as = "MapSkipError<DisplayFromStr, _>")] value: BTreeMap<u32, String>, // Only deserializes entries with a numerical key and a string value, i.e., {0 => "v0", 5 => "v5"}
