Struct rustc_middle::ty::adjustment::CoerceUnsizedInfo

pub struct CoerceUnsizedInfo {
    pub custom_kind: Option<CustomCoerceUnsized>,
}

Information for CoerceUnsized impls, storing information we have computed about the coercion.

This struct can be obtained via the coerce_impl_info query. Demanding this struct also has the side-effect of reporting errors for inappropriate impls.

Fields

custom_kind: Option<CustomCoerceUnsized>

If this is a “custom coerce” impl, then what kind of custom coercion is it? This applies to impls of CoerceUnsized for structs, primarily, where we store a bit of info about which fields need to be coerced.

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.
