Analyzer makecopy ¶

makecopy: detect make+copy that can be simplified to slices.Clone

This analyzer flags two-statement patterns where a slice is allocated with make and immediately populated with copy:

dst := make([]T, len(src))
copy(dst, src)

These can be replaced with the simpler:

dst := slices.Clone(src)

Available since Go 1.21.
