Trait Database

pub trait Database {
    // Required methods
    fn tget<T: Table>(&self, k: &T::Key) -> Option<T>;
    fn trange<T: Table>(&self, range: Range<&T::Key>) -> Vec<T>;
    fn tput<T: Table>(&self, k: &T::Key, v: &T) -> Option<T>;
    fn tscan<T: Table>(&self) -> Vec<T>;
}

Trait denoting an engine capable of providing storage for tables

Required Methods

fn tget<T: Table>(&self, k: &T::Key) -> Option<T>

Serializes the key and retrieves what was stored using this key

fn trange<T: Table>(&self, range: Range<&T::Key>) -> Vec<T>

fn tput<T: Table>(&self, k: &T::Key, v: &T) -> Option<T>

Serializes the key and value using proper formats(Big endian for key, little endian for values) and safely stores this entry in the database

fn tscan<T: Table>(&self) -> Vec<T>

Performs a full table scan of a specified table

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.
