Struct rustc_middle::mir::query::ConstQualifs

pub struct ConstQualifs {
    pub has_mut_interior: bool,
    pub needs_drop: bool,
    pub custom_eq: bool,
    pub error_occured: Option<ErrorReported>,
}

The result of the mir_const_qualif query.

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

Fields

has_mut_interior: bool

needs_drop: bool

custom_eq: bool

error_occured: Option<ErrorReported>

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
