ittapi

This crate allows Rust programs to use Intel® Instrumentation and Tracing Technology (ITT) APIs. Currently, the following APIs are supported (please submit an issue or PR for additional support):

• a JIT notification API, a higher-level view of the C JIT Profiling API
• the Domain API
• the Task API
• the String Handle API
• the Event API
• the Collection Control API

This uses the ittapi-sys crate which depends on the C ittapi library.

IMPORTANT NOTE: this crate is currently only tested on Linux, macOS, and Windows platforms but support for other platforms is intended; contributions are welcome! FreeBSD and OpenBSD are supported but untested.
