Empty slice declared using a literal
Reports slice declarations with empty literal initializers used instead of nil
.
An empty slice can be represented by nil
or an empty slice literal. They are functionally equivalent — their len
and cap
are both zero — but the nil slice is the preferred style. For more information about empty slices, refer to Declaring Empty Slices at github.com/golang.
Example:
s := []string{}
To change the declaration, use the Replace with nil slice declaration (changes semantics) quick-fix. After the quick-fix is applied:
var s []string
