Expand description

Assert a ::std::fs::read_to_string(path) value is less than or equal to an expression.

Pseudocode:
std::fs::read_to_string(path) ≤ expr

  • If true, return (path_into_string, expr_into_string).

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

§Examples

use assertables::*;
use std::io::Read;

let path = "alfa.txt";
let x = "bravo\n";
assert_fs_read_to_string_le_x!(path, x);

// This will panic
let path = "bravo.txt";
let x = "alfa\n";
assert_fs_read_to_string_le_x!(path, x);
// assertion failed: `assert_fs_read_to_string_le_x!(a_path, b_expr)`
// https://docs.rs/assertables/…/assertables/macro.assert_fs_read_to_string_le_x.html
//  a_path label: `path`,
//  a_path debug: `\"bravo.txt\"`,
//  b_expr label: `x`,
//  b_expr debug: `\"alfa\\n\"`,
//      a string: `\"bravo\\n\"`,
//      b string: `\"alfa\\n\"`
