json-rust v0.12.0 Release Notes

Release Date: 2019-09-06 // over 4 years ago
    • ⚡️ Updated to edition 2018.
    • Simplified reading escaped unicode in strings a bit.
    • Provided From<&[T]> implementation for JsonValue where T: Into<JsonValue> (closes #160).
    • object! and array! macros will no longer re-allocate (closes #159).
    • object! and array! macros can be now used without being imported into local scope (by using json::object! or json::array!, thanks @matthias-t).
    • 💥 BREAKING HashMap and BTreeMap conversions are now more generic, working for any pair of K key and V value where K: AsRef<str> and V: Into<JsonValue>. This means that type inference won't always work in your favor, but should be much more flexible.
    • You can now .collect() an interator of (K, V) (with bounds same as point above) into an Object.
