ferrijs-std 0.2.4

Node and web standard library for the ferrijs QuickJS runtime: WHATWG Streams, Events, AbortController, Buffer, crypto, fs, os, url, zlib and the capability model they enforce (partly derived from awslabs/llrt, Apache-2.0).

//! Vendored subset of [awslabs/llrt](https://github.com/awslabs/llrt)
//! (Apache-2.0): the WHATWG Streams implementation plus the pieces it
//! needs (`llrt_utils`, `llrt_events`, `llrt_exceptions`, `llrt_abort`).
//!
//! Upstream crate -> module here:
//!
//! | upstream            | module        |
//! |---------------------|---------------|
//! | `llrt_utils`        | [`utils`]     |
//! | `llrt_context`      | [`context`]   |
//! | `llrt_exceptions`   | [`exceptions`]|
//! | `llrt_events`       | [`events`]    |
//! | `llrt_abort`        | [`abort`]     |
//! | `llrt_os`           | [`os`]        |
//! | `llrt_fs`           | [`fs`]        |
//! | `llrt_path` (helpers)| [`pathutil`] |
//! | `llrt_encoding`     | [`encoding`]  |
//! | `llrt_buffer`       | [`buffer`]    |
//! | `llrt_json`         | [`json`]      |
//! | `llrt_crypto`       | [`crypto`]    |
//! | `llrt_stream_web`   | [`stream_web`]|
//! | `llrt_zlib`         | [`zlib`]      |
//! | `llrt_compression`  | [`compression`]|
//! | `llrt_string_decoder`| [`string_decoder`]|
//! | `llrt_perf_hooks`   | [`perf_hooks`]|
//! | `llrt_tty`          | [`tty`]       |
//! | `llrt_navigator`    | [`navigator`] |
//! | `llrt_url`          | [`url`]       |
//! | `llrt_util` (codecs)| [`text`]      |
//! | `llrt_test`         | `test` (dev)  |
//!
//! Sources are kept byte-close to upstream — only `crate::` / `llrt_*`
//! path prefixes are rewritten — so a re-sync stays a mechanical diff.
//! Host-specific behaviour belongs in the embedding runtime, not here.
