Bump json from 0.11.15 to 0.12.4

[dependabot-preview]

Bumps json from 0.11.15 to 0.12.4.

Release notes

Sourced from json's releases.

0.12.4

• Fixes an issue with new macros requiring types to be copy.

0.12.3

• Improved macro syntax:
  • Object "key" => value pair can be now written as either "key": value or key: value without quotes, as long as key is an identifier.
  • If you want to use the value of the a variable as a key in the new notation, use [foo]: value.
  • When nesting objects or arrays, it's no longer necessary to use invoke array! or object! from within another macro.
  • null is a keyword inside of either macro.
  • This is a backwards compatible change, although mixing notations within a single macro invocation is not permitted.

Example

Instead of:

let obj = object! {
    "foo" => array![1, 2, json::Null],
    "bar" => 42
};

You can now write:

let obj = object! {
    foo: [1, 2, null],
    bar: 42
};

0.12.2

• Fixes #152 & #153.
• Fixed a whole bunch of warnings and some formatting.

0.12.1

• Fixes panics in string generation (#168).
• Fixes an old link to documentation in doc comments (#170).

0.12.0

• 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.
