Trait Decodable

pub trait Decodable: Sized {
    type Target;
    type Error: Error + Sync + Send + 'static;

    // Required method
    fn decode(data: &[u8]) -> Result<Self::Target, Self::Error>;

    // Provided method
    fn decode_bytes(data: Bytes) -> Result<Self::Target, Self::Error> { ... }
}

Determines how a response is decoded.

Required Associated Types

type Target

Target type to decode to.

type Error: Error + Sync + Send + 'static

Error which can occur when attempting to decode data.

Required Methods

fn decode(data: &[u8]) -> Result<Self::Target, Self::Error>

Decode data from a byte slice.

Provided Methods

fn decode_bytes(data: Bytes) -> Result<Self::Target, Self::Error>

Decode data from Bytes.

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.
