Struct rustc_expand::base::DummyResult[−][src]

pub struct DummyResult {
    is_error: bool,
    span: Span,
}
Expand description

Fill-in macro expansion result, to allow compilation to continue after hitting errors.

Fields

is_error: boolspan: Span

Implementations

impl DummyResult[src]

pub fn any(span: Span) -> Box<dyn MacResult + 'static>[src]

Creates a default MacResult that can be anything.

Use this as a return value after hitting any errors and calling span_err.

pub fn any_valid(span: Span) -> Box<dyn MacResult + 'static>[src]

Same as any, but must be a valid fragment, not error.

pub fn raw_expr(sp: Span, is_error: bool) -> P<Expr>[src]

A plain dummy expression.

pub fn raw_pat(sp: Span) -> Pat[src]

A plain dummy pattern.

pub fn raw_ty(sp: Span, is_error: bool) -> P<Ty>[src]

A plain dummy type.
