env_logger sample

This sample shows how to use env_logger in an Rust-SGX enclave. We maintain a SGX fork of [env_logger] at:

https://github.com/mesalock-linux/env_logger-sgx

It is keep updated with its upstream's Github repo. It depends on a SGX fork of log at:

https://github.com/mesalock-linux/log-sgx

Usage of Sample code

$ make
$ cd bin
$ RUST_LOG=trace ./app

$ make
$ cd bin
$ RUST_LOG=info ./app

Usage

• To use env_logger, one must be sure the TCSPolicy is 0.

• To use env_logger, one must include sgx_env.edl in the enclave's EDL file.

• In Cargo.toml, bring in log and env_logger:

log = { git = "https://github.com/mesalock-linux/log-sgx" }
env_logger = { git = "https://github.com/mesalock-linux/env_logger-sgx" }

• Import log and env_logger as usual:

#[macro_use] extern crate log
extern crate env_logger;

• Initialize and log as usual

env_logger::init();

info!("starting up");

• See the log output

$ make
$ cd bin
$ RUST_LOG=trace ./app
