[#Assume]
= Assume
:mrdocs:

Assume is the identity function.

== Synopsis

Declared in `<util/check.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
#define Assume(val)

----

== Description

* Should be used to run non‐fatal checks. In debug builds it behaves like Assert()/assert() to notify developers and testers about non‐fatal errors. In production it doesn't warn or log anything.
* For fatal errors, use Assert().
* For non‐fatal errors in interactive sessions (e.g. RPC or command line interfaces), CHECK_NONFATAL() might be more appropriate.

== Parameters
