stringbytesroundtrip

Overview ¶

Package stringbytesroundtrip implements a Go analysis linter that flags two related but semantically distinct patterns:

• string([]byte(s)) when the result and s have the predeclared string type: genuinely redundant — the result is value-identical to s and both conversions can be removed. For named string types, the inner conversion can still be removed, but an outer conversion may be necessary.
• []byte(string(b)) when b is already a []byte: not redundant but wasteful — this is the defensive-copy idiom that produces a non-aliasing clone via two copies; prefer slices.Clone(b) or bytes.Clone(b) for a single copy.
