Expand description

Assert a std::fs::read_to_string(path) value is greater than an expression.

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

  • If true, return ().

  • 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 = "bravo.txt";
let value = String::from("alfa\n");
assert_fs_read_to_string_gt_expr!(&path, &value);

// This will panic
let path = "alfa.txt";
let value = String::from("bravo\n");
assert_fs_read_to_string_gt_expr!(&path, &value);
// assertion failed: `assert_fs_read_to_string_gt_expr!(a_path, b_expr)`
// https://docs.rs/assertables/8.18.0/assertables/macro.assert_fs_read_to_string_gt_expr.html
//  a_path label: `&path`,
//  a_path debug: `\"alfa.txt\"`,
//  b_expr label: `&value`,
//  b_expr debug: `\"bravo\\n\"`,
//      a string: `\"alfa\\n\"`,
//      b string: `\"bravo\\n\"`
