Hi I'm just learning Go since the last view days, read some docs and noted that its something about defining struct or interface. Still cant get the difference between
var result []Struct
and
result := Struct{}
Is there particular docs I can refer to?
分享 The result in the first example is a nil slice. The spec says that variables are initialized to their zero values and that zero value of a slice is nil.
The result in the second example is a Struct value. It uses a short variable declaration and composite literal value for a Struct. The second example identical to
var result Struct
Perhaps you meant to write
result := []Struct{}
for the second example. This is a non-nil zero length slice. The expression []Struct{} is a composite literal for an empty slice of Struct.
