`ZeroCopyBuf` was convenient to use, but sometimes it did hide details that some copies were necessary in certain cases. Also it made it way to easy for the caller to pass around and convert into different values. This commit splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and `ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer). As a result some magical conversions were removed (they were never used) limiting the API surface and preparing for changes in #19534. |

deno_runtime crate
This is a slim version of the Deno CLI which removes typescript integration and various tooling (like lint and doc). Basically only JavaScript execution with Deno's operating system bindings (ops).
Stability
This crate is built using battle-tested modules that were originally in deno
crate, however the API of this crate is subject to rapid and breaking changes.
MainWorker
The main API of this crate is MainWorker. MainWorker is a structure
encapsulating deno_core::JsRuntime with a set of ops used to implement Deno
namespace.
When creating a MainWorker implementors must call MainWorker::bootstrap to
prepare JS runtime for use.
MainWorker is highly configurable and allows to customize many of the
runtime's properties:
- module loading implementation
- error formatting
- support for source maps
- support for V8 inspector and Chrome Devtools debugger
- HTTP client user agent, CA certificate
- random number generator seed
Worker Web API
deno_runtime comes with support for Worker Web API. The Worker API is
implemented using WebWorker structure.
When creating a new instance of MainWorker implementors must provide a
callback function that is used when creating a new instance of Worker.
All WebWorker instances are descendents of MainWorker which is responsible
for setting up communication with child worker. Each WebWorker spawns a new OS
thread that is dedicated solely to that worker.
