Rust binding for bcc.

Pre-requisites

• bcc must be installed before using this binding.

Supported bcc versions

bcc 0.4.0 - 0.15.0 are supported via feature flags.

Note: If you do not specify a version of bcc using feature flags, the library will expect the latest version of bcc supported by the release of this library. You must specify a version using the matching feature flag to override this behavior.

Generating new bindings

Freshly generated bindings will sometimes be required:

• to support new versions of bcc
• to regenerate older bindings with a newer version of bindgen

How to generate new bindings

Before you generate fresh bindings, you should have rustfmt installed on your system. Install rustfmt with:

$ rustup component add rustfmt
$ rustup update

You may then build this crate using: cargo build --features generate

The fresh bindings will be placed into src/bccapi/generated.rs

NOTE: you may need to make changes to build.rs and/or wrapper.h to add support for a new version of bcc

Adding newly generated bindings

To use the newly generated bindings, we must add them to the library.

• Move your generated bindings to a version specific module under src/bccapi. Follow existing naming conventions.
• If you've added bindings for a new version:
• Modify src/bccapi/mod.rs to add the new module to this library.
• Modify Cargo.toml to define a feature for the new bcc version.
