Module assertables::assert
source · Expand description
Assert a condition is true.
Pseudocode:
condition
-
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.
