Trait ProjectionEvent 

pub trait ProjectionEvent: Sized {
    const EVENT_KINDS: &'static [&'static str];

    // Required method
    fn from_stored<C: Codec>(
        kind: &str,
        data: &[u8],
        codec: &C,
    ) -> Result<Self, EventDecodeError<C::Error>>;
}

Trait for event sum types that can deserialize themselves from stored events.

Implemented by event enums to deserialize stored events.

Deriving Aggregate includes a ProjectionEvent implementation for the generated sum type. Custom enums can opt in manually using the pattern illustrated below.

Required Associated Constants

const EVENT_KINDS: &'static [&'static str]

The list of event kinds this sum type can deserialize.

This data is generated automatically when using the derive macros.

Required Methods

fn from_stored<C: Codec>( kind: &str, data: &[u8], codec: &C, ) -> Result<Self, EventDecodeError<C::Error>>

Deserialize an event from stored representation.

Errors

Returns EventDecodeError::UnknownKind if the event kind is not recognized, or EventDecodeError::Codec if deserialization fails.

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.
