Trait Element 

pub trait Element: Sized {
    const DATA_TYPE: KeyDataType;

    // Required methods
    fn append_to(&self, key: &mut TupleKey);
    fn parse_from(buf: &[u8]) -> Result<Self, &'static str>;

    // Provided method
    fn key_data_type(&self) -> KeyDataType { ... }
}

Required Associated Constants

const DATA_TYPE: KeyDataType

Required Methods

fn append_to(&self, key: &mut TupleKey)

fn parse_from(buf: &[u8]) -> Result<Self, &'static str>

Provided Methods

fn key_data_type(&self) -> KeyDataType

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.
