Trait DagCodec 

pub trait DagCodec<B: BackendExt>: Sized {
    type Error;

    // Required methods
    fn encode(self) -> Result<B::Compact, Self::Error>;
    fn decode(response: &B::Compact) -> Result<Self, Self::Error>;
}

An entry trait that handles the values of a fan-in/fanout entry

Required Associated Types

type Error

The codec error

Required Methods

fn encode(self) -> Result<B::Compact, Self::Error>

Encode the input into a Vec

fn decode(response: &B::Compact) -> Result<Self, Self::Error>

Decode the previous input

Dyn Compatibility

This trait is not dyn compatible.

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