Trait Table 

pub trait Table:

    + Sync
    + Debug
    + 'static {
    type Key: Key;
    type Value: Value;

    const NAME: &'static str;
    const DUPSORT: bool;
    const TABLE: Option<Tables> = None;
}

Generic trait that a database table should follow.

The Table::Key and Table::Value types should implement Encode and Decode when appropriate. These traits define how the data is stored and read from the database.

It allows for the use of codecs. See crate::models::ShardedKey for a custom implementation.

Required Associated Constants

const NAME: &'static str

The table’s name.

const DUPSORT: bool

Whether the table is also a DUPSORT table.

Provided Associated Constants

const TABLE: Option<Tables> = None

The Tables entry this table is stored in, or None for tables defined outside of Tables.

Database implementations use it to find per-table state by position instead of by Self::NAME. A table that reuses the name of a Tables entry must return that entry.

Required Associated Types

type Key: Key

Key element of Table.

Sorting should be taken into account when encoding this.

type Value: Value

Value element of Table.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
