Trait FromEventData

pub trait FromEventData: Sized {
    type Err: Error;

    // Required method
    fn from_data<S: AsRef<[u8]>>(data: S) -> Result<Self, Self::Err>;

    // Provided method
    fn only_id() -> bool { ... }
}

Required Associated Types

type Err: Error

Required Methods

fn from_data<S: AsRef<[u8]>>(data: S) -> Result<Self, Self::Err>

Provided Methods

fn only_id() -> bool

only pass the event id to from_data

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
