I think adding this clarification could potentially help some beginners like myself without being overly verbose. --- compiler/rustc_error_codes/src/error_codes/E0716.md | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/compiler/rustc_error_codes/src/error_codes/E0716.md b/compiler/rustc_error_codes/src/error_codes/E0716.md index c3546cd744f..b50c8b8e7ca 100644 --- a/compiler/rustc_error_codes/src/error_codes/E0716.md +++ b/compiler/rustc_error_codes/src/error_codes/E0716.md @@ -30,8 +30,9 @@ let q = p; Whenever a temporary is created, it is automatically dropped (freed) according to fixed rules.
