Trait LateField 

pub unsafe trait LateField<S: LateStruct>:
    Sized
    + 'static
    + LateFieldSealed<S> {
    type Value: 'static + Default;

    // Required methods
    fn raw_descriptor() -> &'static RawLateFieldDescriptor;
    fn coerce(value: *mut Self::Value) -> *mut S::EraseTo;

    // Provided method
    fn descriptor() -> &'static LateFieldDescriptor<S> { ... }
}

A trait for a marker type representing a field in a late-initialized structure.

This trait cannot be implemented manually. Instead, it should be implemented using the late_field! macro. Most documentation for this trait can be found there.

Safety

This trait can only be safely implemented through the late_field! macro.

Required Associated Types

type Value: 'static + Default

The type of this field’s value.

Required Methods

fn raw_descriptor() -> &'static RawLateFieldDescriptor

Fetches the untyped descriptor associated with this field.

See LateField::descriptor for a typed version of this method.

fn coerce(value: *mut Self::Value) -> *mut S::EraseTo

Coerces a pointer to the field’s concrete value to its unsized form expected used in LateStruct::EraseTo.

Provided Methods

fn descriptor() -> &'static LateFieldDescriptor<S>

Fetches the strongly-typed descriptor associated with this field.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
