Function deserialize

pub fn deserialize<'de, D, K, V, S>(
    deserializer: D,
) -> Result<IndexMap<K, V, S>, D::Error>
where
    D: Deserializer<'de>,
    K: Deserialize<'de> + Eq + Hash,
    V: Deserialize<'de>,
    S: Default + BuildHasher,

Deserializes an IndexMap from an ordered sequence.

This function may be used in a field attribute for deriving Deserialize:

#[derive(Deserialize)]
struct Data {
    #[serde(deserialize_with = "indexmap::map::serde_seq::deserialize")]
    map: IndexMap<i32, u64>,
    // ...
}
