Building from Sources

To build the CLI app from sources, run:

cargo install --locked externref-cli
# This will install `externref` executable, which can be checked
# as follows:
externref --help

This requires a Rust toolchain locally installed.

Minimum supported Rust version

The crate supports the latest stable Rust version. It may support previous stable Rust versions, but this is not guaranteed.

Crate feature: tracing

By default, tracing is enabled via the tracing crate feature. You can disable the feature manually by adding a --no-default-features arg to the installation command. Tracing is performed with the externref::* targets, mostly on the DEBUG and INFO levels. Tracing events are output to the stderr using the standard subscriber; its filtering can be configured using the RUST_LOG env variable (e.g., RUST_LOG=externref=debug).
