Function `dmd.safe.setUnsafePreview`

Like setUnsafe, but for safety errors still behind preview switches


						
				bool setUnsafePreview(
				
  dmd.dscope.Scope* sc,
				
  FeatureState fs,
				
  bool gag,
				
  Loc loc,
				
  const(char)* format,
				
  scope RootObject[] args...
				

				);

Given a FeatureState fs, for example dip1000 / dip25 / systemVariables, the behavior changes based on the setting:

- In case of -revert=fs, it does nothing. - In case of -preview=fs, it's the same as setUnsafe - By default, print a deprecation in @safe functions, or store an attribute violation in inferred functions.

Parameters

Name	Description
sc	used to find affected function/variable, and for checking whether we are in a deprecated / speculative scope
fs	feature state from the preview flag
gag	surpress error message
loc	location of error
format	printf-style format string
args	arguments for format string

Returns

whether an actual safe error (not deprecation) occured
