Function deserialize_nullish

lambda-events/src/custom_serde/mod.rs:67–74

Deserializes any `Default` type, mapping JSON `null` to `T::default()`. Note** null-to-empty semantics are usually clear for container types (Map, Vec, etc). For most other data types, prefer modeling fields as ```Option ``` with #[serde(default)] instead of using this deserializer. Option preserves information about the message for the application, and default semantics for the target data typ

(deserializer: D)

/// for the application, and default semantics for the target data type may change
/// over time without warning.
pub(crate) fn deserialize_nullish<'de, D, T>(deserializer: D) -> Result<T, D::Error>
where
    D: Deserializer<'de>,
    T: Default + Deserialize<'de>,
{
    let opt = Option::deserialize(deserializer)?;
    Ok(opt.unwrap_or_default())
}
