Definition of Sqlable trait to be implemented to allow interaction with SQL tables.

Required Associated Types

type Item

Defines the struct corresponding to the items in the SQL table

type Error

Defines the struct used for returning errors

type Selector

Defines the struct used for providing selection, filtering to the implementation of the trait

Required Methods

fn count(&self, s: Self::Selector) -> Result<usize, Self::Error>

Count the number of items in the table meeting the selector requirements

fn select(&self, s: Self::Selector) -> Result<Vec<Self::Item>, Self::Error>

Retrieve the array of items in the table meeting the selector requirements

fn insert(&mut self, item: Self::Item) -> Result<Self::Item, Self::Error>

Insert a new item in the table and returned the inserted item.

fn update( &mut self, s: Self::Selector, item: Self::Item ) -> Result<Self::Item, Self::Error>

Update items meeting the selector requirements with the values of the provided item. Returns the array of items modified with their updated value

fn delete(&mut self, s: Self::Selector) -> Result<(), Self::Error>

Delete items in the table meeting the selector requirements

fn delete_table(&mut self) -> Result<(), Self::Error>

Delete the table from the database
