let uncompressed_size = data.uncompressed_size as usize;
/* We already know *exactly* how many bytes we will need to read out
* (because this info is recorded in the zip file entryu), so we can
* allocate exactly that much to minimize allocation as well as
* blocking on memory availability for the decompressor. */
they literally don't want you to know this about zip files
/* (4) In order, scan off the raw memory for every file entry into a Box<[u8]> to avoid
* interleaving decompression with read i/o. */
this one comment is literally the entire game if anyone would listen to me
lmao a literal word-for-word async implementation of the zip file spec that i completely forgot i did. i think that bumps the count to 4 times i've implemented the zip spec https://github.com/cosmicexplorer/zip/blob/f755697eff4f342c842e2c76ae2bb387515de56b/src/tokio/read.rs#L1102 i guess it would be hard for astral without that expertise
