Struct rustc_lint::builtin::TrivialConstraints

pub struct TrivialConstraints;

Lint for trait and lifetime bounds that don’t depend on type parameters which either do nothing, or stop the item from being used.

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.
