Macro assert_len_eq

macro_rules! assert_len_eq {
    ($a:expr, $b:expr $(,)?) => { ... };
    ($a:expr, $b:expr, $($message:tt)+) => { ... };
}

Assert a length is equal to another length.

Pseudocode:
a.len() = b.len()

• If true, return ().

• Otherwise, call panic! with a message and the values of the expressions with their debug representations.

Examples

use assertables::*;

let a = "x";
let b = "x";
assert_len_eq!(a, b);

let a = "x";
let b = "xx";
assert_len_eq!(a, b);
// assertion failed: `assert_len_eq!(a, b)`
// https://docs.rs/assertables/8.14.0/assertables/macro.assert_len_eq.html
//  a label: `a`,
//  a debug: `\"x\"`,
//  a.len(): `1`",
//  b label: `b`,
//  b debug: `\"xx\"`,
//  b.len(): `2`"
