Macro debug 

macro_rules! debug {
    ($expr:expr) => { ... };
    ($($val:expr),+ $(,)?) => { ... };
}

A debug macro that prints the expression and its value to stderr.

This macro is a more gas-efficient alternative to the standard dbg! macro. It evaluates the given expression, prints the source location, expression text, and its debug representation to standard error.

Examples

use seda_sdk_rs::debug;

let a = 2;
let b = debug!(a * 2) + 1;
// Prints to stderr: [src/main.rs:2:9] a * 2 = 4
assert_eq!(b, 5);

Multiple values can be debugged at once:

use seda_sdk_rs::debug;

let x = 1;
let y = 2;
debug!(x, y, x + y);
// Prints each value on a separate line with location information

Notes

This macro requires that the expression’s type implements the Debug trait.
