Rust binding for bcc.
Pre-requisites
- bcc must be installed before using this binding.
Supported bcc versions
- Version 0.6.0 reflects the 0.5.0 version of bcc.
- Version 0.7.0 reflects the 0.6.1 version of bcc.
- Version 0.7.1 reflects the 0.6.1 version of bcc.
- Version 0.8.0 reflects bcc v0.4.0-v0.8.0 using feature flags.
- Version 0.9.0 reflects bcc v0.4.0-v0.9.0 using 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.
