firedbg-lib 0.1.2

FireDBG Support Library

fire::dbg!

This macro allows you to capture the value of a variable via runtime inspection in FireDBG.

Usage example:

use firedbg_lib::fire;

fn some_fn(v: i32) -> i32 {
    fire::dbg!(v) + 1
}

fn other_fn(v: i32) -> i32 {
    fire::dbg!("arg_v", v) + 1
}

Which fire::dbg!(v) would expand to __firedbg_trace__("v", v) when compiled under debug mode. The label could be customized, which fire::dbg!("arg_v", v) would expand to __firedbg_trace__("arg_v", v). In release mode, it would expand to an expression passing through the value, i.e. { v }.

Note that the function passes through the ownership of the variable, just like the std::dbg! macro.

fn __firedbg_trace__<T>(name: &'static str, v: T) -> T { v }
