How to run Rust code from Elixir with --release mode?
Hi,
I need to read millions rows via rust , do some modification and return final result (some stats) to elixir apps via rustler .
When I run rust code with :
cargo run it takes 40 sec.
cargo run --realease it takes 1,5 sec.
but when I run it from Elixir via rustler/nif from iex -S mix it takes 40 sec.
How to run it so fast in similar way like cargo run --release mode, from elixir apps ?
Thanks for help .

Rustler by default uses the
MIX_ENVto determine how to build the nif, if you’re usingiex -S mixthe defaultMIX_ENVis:dev, which compiles the nif in debug mode (the 40 seconds use case).To compile the nif in release mode you can either pass the
MIX_ENVto the iex commandMIX_ENV="prod" iex -S mixor you can passmode: :releasein the nif config itself, the config options can be found here.Last Post!
