This PR makes json_op_sync/async generic to all Deserialize/Serialize types instead of the loosely-typed serde_json::Value. Since serde_json::Value implements Deserialize/Serialize, very little existing code needs to be updated, however as json_op_sync/async are now generic, type inference is broken in some cases (see cli/build.rs:146). I've found this reduces a good bit of boilerplate, as seen in the updated deno_core examples. This change may also reduce serialization and deserialization overhead as serde has a better idea of what types it is working with. I am currently working on benchmarks to confirm this and I will update this PR with my findings. |

Deno Core Crate
The main dependency of this crate is rusty_v8, which provides the V8-Rust bindings.
This Rust crate contains the essential V8 bindings for Deno's command-line interface (Deno CLI). The main abstraction here is the JsRuntime which provides a way to execute JavaScript.
The JsRuntime implements an event loop abstraction for the executed code that
keeps track of all pending tasks (async ops, dynamic module loads). It is user's
responsibility to drive that loop by using JsRuntime::run_event_loop
method -
it must be executed in the context of Rust's future executor (eg. tokio, smol).
In order to bind Rust functions into JavaScript, use the Deno.core.dispatch()
function to trigger the "dispatch" callback in Rust. The user is responsible for
encoding both the request and response into a Uint8Array.
Documentation for this crate is thin at the moment. Please see http_bench_bin_ops.rs and http_bench_json_ops.rs as a simple example of usage.
TypeScript support and a lot of other functionality is not available at this layer. See the CLI for that.
