[−][src]Enum syntax_pos::hygiene::CompilerDesugaringKind
The kind of compiler desugaring.
Variants
IfTemporary
We desugar if c { i } else { e }
to match $ExprKind::Use(c) { true => i, _ => e }
.
However, we do not want to blame c
for unreachability but rather say that i
is unreachable. This desugaring kind allows us to avoid blaming c
.
