This commit adds a new op_write_all to core that allows writing an entire chunk in a single async op call. Internally this calls `Resource::write_all`. The `writableStreamForRid` has been moved to `06_streams.js` now, and uses this new op. Various other code paths now also use this new op. Closes #16227 |

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).
Rust functions can be registered in JavaScript using deno_core::Extension
. Use
the Deno.core.opSync()
and Deno.core.opAsync()
functions to trigger the op
function callback. A conventional way to write ops is using the
deno_ops
crate.
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.
