dump

dump provides a macro dump! that takes one or more variables and prints the name, type, and value of each variable. The output is also prefixed with [source_file:line_no].

This is designed to be a little more ergonomic than println!("a={:?} b={:?}", a, b) and also has the benefit of printing the type.

Usage

Add this to your Cargo.toml:

toml [dependencies] dump = "0.1"

and this to your crate root:

```rust

[macro_use]

extern crate dump; ```

Example

```rust

[macro_use]

extern crate dump;

fn main() { let s = "hi"; let n = 3; dump!(s, n); } ```

Outputs:

[src/main.rs:7] s: &'static str = "hi"; n: i32 = 3;
