Struct ConstQualifs

pub struct ConstQualifs {
    pub has_mut_interior: bool,
    pub needs_drop: bool,
    pub needs_non_const_drop: bool,
    pub tainted_by_errors: Option<ErrorGuaranteed>,
}

The result of the mir_const_qualif query.

Each field (except tainted_by_errors) corresponds to an implementer of the Qualif trait in rustc_const_eval/src/transform/check_consts/qualifs.rs. See that file for more information on each Qualif.

Fields

has_mut_interior: bool

needs_drop: bool

needs_non_const_drop: bool

tainted_by_errors: Option<ErrorGuaranteed>

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.
