Expand description
Assert a command (built with program and args) stderr string is not equal to an expression.
Pseudocode:
(program1 + args1 ⇒ command ⇒ stderr ⇒ string) ≠ (expr into string)
-
If true, return Result
Ok(())
. -
Otherwise, return Result
Err
with 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.
