Derive Macro Decode 

#[derive(Decode)]
{
    // Attributes available to this derive:
    #[codec]
}

Available on crate feature ipc only.

Derive the Decode trait for a message.

A #[codec(..)] attribute must be present to select the deserialization method and the same attribute is shared with Decode. Encoding and decoding of the same message type must use the same method. The attribute also supports an optional bridge type that serves as an intermediary for encoding and decoding, which is useful when the message type itself cannot directly implement the required traits. Currently there are three supported codec methods:

• #[codec(prost)] — delegates to prost::Message::decode. The target type (or the bridge type) must implement prost::Message.
• #[codec(zerocopy)] — delegates to zerocopy::FromBytes::read_from_bytes. The target type (or the bridge type) must implement zerocopy::FromBytes.
• #[codec(rkyv)] — delegates to rkyv::from_bytes. The target type (or the bridge type) must implement rkyv::Archive and rkyv::Deserialize.

If a bridge type T is specified, the target type must be convertible from the bridge type with impl TryFrom<T> for Self and use DecodeError as the error type.

Example

use acktor_derive::Decode;

#[derive(zerocopy::FromBytes, Decode)]
#[codec(zerocopy)]
struct Ping(u64);
