Hi @cprussin, I wouldn't accept a PR but only because it is already planned.
Expect a load_opt
function with a Result<Option<PathBuf>>
signature. It will return Error
if there was an error reading the file, return Ok(Some(PathBuf))
if the file is read correctly, and Ok(None)
if the file is not found.
Oh that's awesome, thanks @allan2 and sorry I missed that, I searched around but I didn't see that discussion.
Is there anything blocking getting that added? I'm happy to submit the PR adding it if we're just waiting on a contributor. load_opt
would be basically the snippet I posted above, except for passing through the PathBuf
inside an Option
in the first arm and the None
in the second arm of course.
Hi, I find the following to be a really useful function that I've started copying around to a few places:
Basically, load a dotenv file, but ignore if the file doesn't exist. However, still return an
Err
for any other error loading the env file.Since I've found this to be something I want nearly always I figure it might be valuable to add it to the crate directly. Just curious @allan2, would you accept a PR to add such a function?
