Expand description
Assert an iterable is less than or equal to another.
Pseudocode:
(collection1 into iter) ≤ (collection2 into iter)
-
If true, return Result
Ok(()). -
Otherwise, return Result
Errwith a diagnostic message.
This macro provides the same statements as assert_,
except this macro returns a Result, rather than doing a panic.
This macro is useful for runtime checks, such as checking parameters, or sanitizing inputs, or handling different results in different ways.
This implementation uses std::iter::Iterator.
