Module assert_len

Assert for comparing lengths.

These macros help with collection lengths, such as for strings, arrays, vectors, iterators, and anything that has a typical .len() method.

Compare a length with another length:

• assert_len_eq!(a, b) ≈ a.len() = b.len()
• assert_len_ne!(a, b) ≈ a.len() ≠ b.len()
• assert_len_lt!(a, b) ≈ a.len() < b.len()
• assert_len_le!(a, b) ≈ a.len() ≤ b.len()
• assert_len_gt!(a, b) ≈ a.len() > b.len()
• assert_len_ge!(a, b) ≈ a.len() ≥ b.len()

Compare a length with an expression:

• assert_len_eq_x!(a, expr) ≈ a.len() = expr
• assert_len_ne_x!(a, expr) ≈ a.len() ≠ expr
• assert_len_lt_x!(a, expr) ≈ a.len() < expr
• assert_len_le_x!(a, expr) ≈ a.len() ≤ expr
• assert_len_gt_x!(a, expr) ≈ a.len() > expr
• assert_len_ge_x!(a, expr) ≈ a.len() ≥ expr

Example

use assertables::*;

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