Trait Packed

pub trait Packed:
    Storable
    + Codec
    + Sealed { }

Trait for describing types that can be read and written to storage while all fields occupy only a single storage cell.

If at least one of the fields in the type occupies its own storage cell, this type is considered non-packed.

Note

The trait is automatically implemented for types that implement scale::Codec via blanket implementation.

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.
