Expand description

Assert a number is within delta of another number.

  • If true, return Result Ok(()).

  • When false, return 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 santizing inputs, or handling different results in different ways.
