overlookmotel 39afb48025 feat(allocator): introduce Vec::from_array_in (#7331) 
Because we lack specialization in stable Rust, `Vec::from_iter_in` is unable to take advantage of the fact that `[T; N]` has a statically knowable size.

Introduce `Vec::from_array_in` for this case, which should be able to create the `Vec` with a single static-sized memcpy, or may allow the compiler to see that it can construct the array directly in the arena, rather than construct on stack and then copy to the arena.

Also add a corresponding `AstBuilder::vec_from_array` method, and use it in various places in codebase.

Minifier

A JavaScript minifier has three components:

  1. printer
  2. mangler
  3. compressor

Mangler

The mangler implementation is part of the SymbolTable residing in oxc_semantic. It is responsible for shortening variables. Its algorithm should be gzip friendly.

The printer is also responsible for printing out the shortened variable names.

Compressor

The compressor is responsible for rewriting statements and expressions for minimal text output. Terser is a good place to start for learning the fundamentals.

Terser Tests

The fixtures are copied from https://github.com/terser/terser/tree/v5.9.0/test/compress
