1287162 - Consider switching FTL parser to Rust

Status: NEW

(L20n :: General, defect)

Description

[Zibi Braniecki [:zbraniecki][:gandalf]]

We have a POC of the Rust parser for FTL at https://github.com/zbraniecki/l20n.rs and endoli is working on extending it in https://github.com/endoli/message-format.rs

First tests indicate that Rust parser is around 100 times faster. Once Gecko has reliable support for Rust we may want to switch to Rust parser.

gandalf, should this really block gecko-l20n? I'm leaning towards no, unless we find a hard blocker here.

No strong opinion here. I wanted to "consider", and that means that once we have things in place, measure Parser cost and if it's significant enough, and plugging in rust is easy enough, we can switch, if not, remove from the dependency or resolve as WONTFIX.

But if it messes with your dependency tree, feel free to remove it :) I'm sure we'll remember about this option anyway as we go through perf testing.

'k, let's move this out of the hot path for now.
