How much space (in bytes) does a Golang interface take up?
For example, which would take up more space?
type Stringer interface { String() string }
strSlice := make([]string, 4)
stringerSlice := make([]Stringer, 4)

- interface consumes 2 words of memory: 1 word for runtime type and 1 word for data pointer;
- string consumes 2 words of memory: 1 word for base pointer and 1 word for length;
- slice consumes 3 words of memory: 1 word for base pointer, 1 word for length and 1 word for capacity;
- function, channel and map consume 1 word.
Based on the machine type(32bit or 64bit) word size is 4 bytes length or 8 bytes length respectively.
