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.
