Struct rustc_errors::ErrorGuaranteed

pub struct ErrorGuaranteed(pub(crate) ());

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.
