- Why does it say
where T: Sized
for references&T
? A reference can definitely point to an unsized type, e.g.&str
.
I think the point being made is that the layout shown only applies for Sized
T
. Layouts for &[T]
and &dyn Trait
are shown elsewhere on the sheet. &str
is noted under &[T]
.
Edit: although, similar considerations would apply to other pointer types, but that isn't noted on the sheet except for Box<[T]>
That code point is U+0D9E SINHALA LETTER KANTAJA NAASIKYAYA. It's a letter in a writing system used in Sri Lanka.
