Trait fuel_core_storage::codec::Encode

pub trait Encode<T: ?Sized> {
    type Encoder<'a>: Encoder
       where T: 'a;

    // Required method
    fn encode(t: &T) -> Self::Encoder<'_>;

    // Provided method
    fn encode_as_value(t: &T) -> Value { ... }
}

The trait encodes the type to the bytes and passes it to the Encoder, which stores it and provides a reference to it. That allows gives more flexibility and more performant encoding, allowing the use of slices and arrays instead of vectors in some cases. Since the Encoder returns Cow<[u8]>, it is always possible to take ownership of the serialized value.

Required Associated Types

type Encoder<'a>: Encoder where T: 'a

The encoder type that stores serialized object.

Required Methods

fn encode(t: &T) -> Self::Encoder<'_>

Encodes the object to the bytes and passes it to the Encoder.

Provided Methods

fn encode_as_value(t: &T) -> Value

Returns the serialized object as an Value.

Object Safety

This trait is not object safe.
