Expand description

Trait for representing types which can be read and written to storage.

This trait is not the same as the scale::Codec. Each type that implements scale::Codec are storable by default and transferable between contracts. But not each storable type is transferable.

Required Methods§

source

fn encode<T: Output + ?Sized>(&self, dest: &mut T)

Convert self to a slice and append it to the destination.

source

fn decode<I: Input>(input: &mut I) -> Result<Self, Error>

Attempt to deserialize the value from input.

Implementors§

source§

impl<P> Storable for Pwhere P: Codec,

Types which implement scale::Encode and scale::Decode are Storable by default because they can be written directly into the storage cell.
