Nilness analyzer
Reports problems caused by incorrect usage of the nil
value.
The IDE analyses data flow to determine if variables could have nil
or not nil
values. Based on this, the IDE reports potential issues in code. Consider the following list of situations that might lead to unintended consequences:
Method calls with the
nil
receiver might lead to 'nil pointer dereference'.The
nil
slice indexing might cause panics.Comparisons like
v == nil
might be meaningless ifv
is known to be alwaysnil
or notnil
.Variables with corresponding errors are not checked on not to be
nil
. An error corresponds to a variable when they are defined or assigned together in statements likev, err := foo()
.
