Expose a function to return the LMDB version #199

Closed Kerollmops closed 1 year ago

Kerollmops commented 1 year ago

I want to expose a very simple function that returns the major, minor, and patch versions of the underlying LMDB library.

fn heed::lmdb_version() -> (major, minor, patch);
postmeback commented 1 year ago

I will give it a try !

Hey @postmeback 👋

Getting error while cargo build

You should read the README when you build from source. You probably forgot to pull the LMDB sources.

And also, where exactly should i write the function ?

Put in at the root of the project, in the heed lib.rs file, please.
