Variants

Ty(Ty<'tcx>)

Expected the binding to have the given type, but it was found to have a different type. Find out when that type first became incompatible.

Arg

Fields

call_expr: &'tcx Expr<'tcx>

incompatible_arg: usize

When we fail during method argument checking, try to find out if a previous expression has constrained the method’s receiver in a way that makes the argument’s type incompatible.

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.
