With the `probe!` macro, programmers can place static instrumentation

points in their code to mark events of interest. These are compiled into

platform-specific implementations, e.g. SystemTap SDT on Linux. Probes are

designed to have negligible overhead during normal operation, so they can

be present in all builds, and only activated using those external tools.

[Documentation](https://docs.rs/probe/)

## Using probe

[`probe!` is available on crates.io](https://crates.io/crates/probe).

The recommended way to use it is to add a line into your Cargo.toml such as:

```toml

[dependencies]

probe = "0.5"

```

Then `use probe::probe;` in your code and insert macro calls wherever you want

to mark something, `probe!(provider, name, args...)`. The `provider` and `name`

are identifiers of your choice, and any additional arguments are runtime

expressions that will be cast `as isize` for the probe consumer to read.

There is also a `probe_lazy!` variant that tries to avoid evaluating the

argument expressions when probes aren't in use, if the platform-specific

implementation allows that to be determined.
