Expand description

Assert a command (built with program and args) stdout string is a match to a regex.

  • 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 santizing inputs, or handling different results in different ways.
