Abort-if crate

The abort_if procedural macro guarantees that a specific function panics if a condition is met.

Example

You can assure that a function won't be used if feature x is enabled

``` use abortif::abortif;

[abort_if(feature = x)]

fn foo() { usingthatfeature(); }

fn main() { foo(); } ```

This code will panic if that feature is enabled.

Features

The default is panicking using compiler_error!. This will output the following information:

error: Condition was met. --> src/main.rs:5:1 | 5 | #[abort_if(feature = "x")] | ^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this error originates in the attribute macro `abort_if` (in Nightly builds, run with -Z macro-backtrace for more info)

You can use the feature custom_abort to write a custom abort macro. When using this feature, make sure to have a custom_abort_error! macro with an expr as the argument.

If you use the custom_abort feature, you can also use the keep_going one. This feature functions that, if your custom_abort_error macro works as a warning instead of a hard error, the code will keep going.
