Module assert_starts_with 

Assert for a sequence that may start with a part.

These macros help with comparison of a sequence (such as a string, vector, range) and a part (such as a string substring, an array element, a range value).

• assert_starts_with(sequence, subsequence) ≈ container.contains(containee)

• assert_not_starts_with!(sequence, subsequence) ≈ !container.contains(containee)

Example

use assertables::*;

// String starts with substring?
let sequence: &str = "alfa";
let subsequence: &str = "al";
assert_starts_with!(sequence, subsequence);

// Vector starts with element?
let sequence = vec![1, 2, 3];
let subsequence = [1];
assert_starts_with!(sequence, subsequence);
