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.


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.

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more
