Struct rustc_span::ErrorGuaranteed
source · pub struct ErrorGuaranteed(pub(crate) ());
Expand description
Useful type to use with Result<>
indicate that an error has already
been reported to the user, so no need to continue checking.
The ()
field is necessary: it is non-pub
, which means values of this
type cannot be constructed outside of this crate.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
