//! ## Introduction
//!
//! This specification defines JSON Predicates, a JSON-based
//! [RFC4627](https://datatracker.ietf.org/doc/html/rfc4627)
//! syntax for the description and serialization of logical boolean
//! predicate operations intended to be used in conjunction with other
//! JSON-based mechanisms, such as JSON Patch [RFC6902](https://datatracker.ietf.org/doc/html/rfc6902),
//! as a means of incorporating conditional processing.
//!
//! JSON Predicates can be used, for instance, to extend a JSON Patch
//! [RFC6902](https://datatracker.ietf.org/doc/html/rfc6902) document to provide
//! for a broader range of conditional processing options not currently supported
//! by JSON Patch.
//!
//! ## Example
//!
//! Given this JSON:
//! ```json
//! {
//! "a": {
//! "b": {
//! "c": "ABC!XYZ"
//! }
//! }
//! }
//! ```
//!
//! We could have a predicate like this:
//! ```json
//! {
//! "op": "and",
//! "path": "/a/b/c",
//! "apply": [
//! {
//! "op": "type",
//! "value": "string"
//! },
//! {
//! "op": "contains",
//! "value": "ABC"
//! }
//! ]
//! }
//! ```
//!
//! which would evaluate as `true` if evaluated against the previous JSON.
//!
//! ## Rust Example
//!
//! ```rust
//! let predicate = Predicate::deserialize(serde_json::json!({
//! "op": "and",
//! "path": "/objA",
//! "apply": [
//! {
//! "op": "defined",
//! "path": "/stringX"
//! },
//! {
//! "op": "defined",
//! "path": "/stringXYZ"
//! }
//! ],
//! }))?;
//!
//! let evaluted_predicate: bool = predicate
//! .test(&ENTRY, PredicateContext::default());
//! ```
//!
//! ## JSON Patch
//!
//! The JSON Patch methods described in [draft-snell-json-test-07](https://datatracker.ietf.org/doc/html/draft-snell-json-test-07)
//! are not implemented yet.
//!
//! ## Features
//!
//! ### First order predicate
//!
//! - [x] "contains"
//! - [x] "contains-"
//! - [x] "defined"
//! - [x] "undefined"
//! - [x] "starts"
//! - [x] "starts-"
//! - [x] "ends"
//! - [x] "ends-"
//! - [x] "type"
//! - [x] "in"
//! - [x] "in-"
//! - [x] "matches"
//! - [x] "matches-"
//! - [x] "test"
//! - [x] "test-"
//! - [x] "less"
//! - [x] "more"
//!
//! ### Second order predicate
//!
//! - [x] "and"
//! - [x] "not"
//! - [x] "or"
//!
