fst VS perl5

I'd point you towards BurntSushi's fst crate: https://github.com/BurntSushi/fst

The fst crate effectively relies on mmap for it to work right. The folks here suggesting you just use the heap might be right, but only if using the heap is actually plausible. If your dictionary is GBs big (an FST might be bigger than available memory), then copying it the heap first would be disastrous.

You'll love what we're working on if you're interested in the implementation of:- Tantivy- Meilisearch- Finite State Transducers

Here's an example of longest prefix matching using a FST which I based my approach on: https://github.com/BurntSushi/fst/pull/104/files

Finite State Transducers

As a result, I have a plan to implement a desktop version from then and I finished today with a beta version. The desktop is based on tauri, and the dictionary index algorithm is FST (it is an awesome index algorithm).

WordBueno’s data is currently derived from Wiktionary. The backend is using Rust’s warp with fst for indexing.

No you don't. I've written multiple programs that load things instantly off the file system via memory maps. See the fst crate[1], for example, which is designed to work with memory maps.

Rust "works badly with memory mapped files" doesn't mean, "Rust can't use memory mapped files." It means, "it is difficult to reconcile Rust's safety story with memory maps." ripgrep for example uses memory maps because they are faster sometimes, and its safety contract[2] is a bit strained. But it works.

I was not signed into GitHub. I opened the permalink and it displayed fine. I opened the raw page in another tab; it was fine.

Nothing to do with a fixing the trap, it turns out: https://github.com/Perl/perl5/commit/4197fe35a33e6471f8f532abfd06cd6c120f180e which leads to https://rt.perl.org/perl5/Ticket/Display.html?id=109408

As we mentioned last week, this week we are working on a portable, symbolic link implementation that also works on Windows. You can see our progress here. To implement this, the Perl win32/win32.c source code would be greatly appreciated.
