Trait Sealed 

pub unsafe trait Sealed {
    type Storage;

    // Required method
    fn new_storage() -> Self::Storage;

    // Provided method
    fn grow(
        _storage: &mut Self::Storage,
        _additional: usize,
    ) -> Result<(), CapacityFull> { ... }
}

Safety

Implementer must not modify the content in storage.

Required Associated Types

type Storage

Required Methods

fn new_storage() -> Self::Storage

Provided Methods

fn grow( _storage: &mut Self::Storage, _additional: usize, ) -> Result<(), CapacityFull>

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.
