[][src]Enum syntax_pos::hygiene::CompilerDesugaringKind

pub enum CompilerDesugaringKind {

The kind of compiler desugaring.



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.


Desugaring of an impl Trait in return type position to an existential type Foo: Trait; and replacing the impl Trait with Foo.
