Struct rustc_expand::base::DummyResult
source · Expand description
Fill-in macro expansion result, to allow compilation to continue after hitting errors.
Fields
is_error: bool
span: Span
Implementations
sourceimpl DummyResult
impl DummyResult
sourcepub fn any(span: Span) -> Box<dyn MacResult + 'static>
pub fn any(span: Span) -> Box<dyn MacResult + 'static>
Creates a default MacResult that can be anything.
Use this as a return value after hitting any errors and
calling span_err
.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
