This commit renames "JsRuntime::execute" to "JsRuntime::execute_script". Additionally same renames were applied to methods on "deno_runtime::Worker" and "deno_runtime::WebWorker". A new macro was added to "deno_core" called "located_script_name" which returns the name of Rust file alongside line no and col no of that call site. This macro is useful in combination with "JsRuntime::execute_script" and allows to provide accurate place where "one-off" JavaScript scripts are executed for internal runtime functions.

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.opSync()
and Deno.core.opAsync()
functions to trigger the "op_fn" callback in
JsRuntime::register_op
on Rust side. A conventional way to handle "op_fn"
callbacks is to use the op_sync
and op_async
functions.
Documentation for this crate is thin at the moment. Please see hello_world.rs and http_bench_json_ops.rs as examples of usage.
TypeScript support and lots of other functionality are not available at this layer. See the CLI for that.
