Struct rustc_trait_selection::traits::query::DropckConstraint

pub struct DropckConstraint<'tcx> {
    pub outlives: Vec<GenericArg<'tcx>, Global>,
    pub dtorck_types: Vec<Ty<'tcx>, Global>,
    pub overflows: Vec<Ty<'tcx>, Global>,
}

A set of constraints that need to be satisfied in order for a type to be valid for destruction.

Fields

outlives: Vec<GenericArg<'tcx>, Global>

Types that are required to be alive in order for this type to be valid for destruction.

dtorck_types: Vec<Ty<'tcx>, Global>

Types that could not be resolved: projections and params.

overflows: Vec<Ty<'tcx>, Global>

If, during the computation of the dtorck constraint, we overflow, that gets recorded here. The caller is expected to report an error.

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.
