Around Crate

This is the around crate, a Rust procedural macro library for calling other functions inside your desired ones.

Getting Started

To use the around crate, add it to your Cargo.toml file:

[dependencies]
around = { version = "0.1.0"}

Usage

The around crate provides a procedural macros before, afer and both that enables running another function when expected.

The function must exist and be in scope.

Here's a basic example of how to use it:

#[around(database_clean)]
fn fancy_func(){
    // Your function code here...
}

In this example database_clean would be called twice, once before and once after your original function code.

Currently this literally translates to:

fn fancy_func(){
    database_clean();
    // Your function code here...
    database_clean();
}
