Enum rustc_parse::parser::ty::RecoverReturnSign[][src]

pub(super) enum RecoverReturnSign {
    Yes,
    OnlyFatArrow,
    No,
}
Expand description

Signals whether parsing a type should recover ->.

More specifically, when parsing a function like:

fn foo() => u8 { 0 }
fn bar(): u8 { 0 }

The compiler will try to recover interpreting foo() => u8 as foo() -> u8 when calling parse_ty with anything except RecoverReturnSign::No, and it will try to recover bar(): u8 as bar() -> u8 when passing RecoverReturnSign::Yes to parse_ty

Variants

Yes

OnlyFatArrow

No

Implementations

RecoverReturnSign::Yes allows for recovering fn foo() => u8 and fn foo(): u8, RecoverReturnSign::OnlyFatArrow allows for recovering only fn foo() => u8 (recovering colons can cause problems when parsing where clauses), and RecoverReturnSign::No doesn’t allow for any recovery of the return type arrow
