Struct CoerceUnsizedInfo

Source

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>

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.
