ittapi-rs

This package contains Rust bindings for the ittapi library--it is equivalent to a crate using the *-sys convention but named differently for historical reasons. The ittapi library is used for various aspects of Intel® profiling; it exposes the Instrumentation and Tracing Technology (ITT) API as well as the Just-In-Time (JIT) Profiling API. More details about ittapi are available on its README.

IMPORTANT NOTE: this package is currently only tested on several Linux platforms (recent Ubuntu and Fedora builds) but support for other platforms is intended; contributions are welcome!

Use

[dependencies]
ittapi = "0.1"

This crate currently uses the parent project's CMake configuration so a local CMake installation (as well as a C compiler) is necessary.

Build

cargo build

Building ittapi-rs will use CMake to build the ittapi library and link it statically into your application; see the build.rs file.

Test

cargo test

This crate's tests ensure the ittapi-rs bindings remain up to date with the official C header files; they do not check ittapi functionality.

Regenerate Bindings

If the ittapi-rs bindings are not up to date, they can be regenerated with:

BLESS=1 cargo test

The binding generation uses bindgen. An in-depth description of how to use bindgen is available in the bindgen documentation.
