Trait EntryProvider 

pub unsafe trait EntryProvider:
    Send
    + Sync
    + 'static {
    // Required method
    fn entry_pointer(&self) -> NonNull<EntryDescriptor>;
}

A type which can provide an entry descriptor pointer for Clack hosts to load.

Safety

Implementors must ensure the EntryDescriptor returned by the entry_pointer method remains valid for the entire lifetime of this type. That means all the function pointers it contains must remain valid to call.

Moreover, the returned EntryDescriptor must have a stable address. It must not move for the lifetime of this type.

Required Methods

fn entry_pointer(&self) -> NonNull<EntryDescriptor>

Returns a pointer to the EntryDescriptor this provides.

This pointer always valid for reads, as long as this type is alive. This pointer is also stable, i.e. its address will never change for the entire duration of this type’s lifetime.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
