Struct rustc_middle::ty::adjustment::CoerceUnsizedInfo[−][src]

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

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>
Expand description

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.
