Expand description
Assert a command (built with program and args) stdout string is not equal to another.
Pseudocode:
(program1 + args1 ⇒ command ⇒ stdout ⇒ string) ≠ (program2 + args2 ⇒ command ⇒ stdout ⇒ string)
-
If true, return
()
. -
If true, return Result
Err
with a message and the values of the expressions with their debug representations.
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.
