Implementations

impl DatabaseBackend

pub fn is_prefix_of(self, base_url: &str) -> bool

Check if the URI is the same as the specified database backend. Returns true if they match.

Panics

Panics if base_url cannot be parsed as Url.

pub fn build<S>(&self, statement: &S) -> Statement

where S: StatementBuilder,

Build an SQL Statement

pub fn get_query_builder(&self) -> Box<dyn QueryBuilder>

A helper for building SQL queries

pub fn support_returning(&self) -> bool

Check if the database supports RETURNING syntax on insert and update

pub fn boolean_value(&self, boolean: bool) -> Value

A getter for database dependent boolean value

Trait Implementations

impl Clone for DatabaseBackend

fn clone(&self) -> DatabaseBackend

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatabaseBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for DatabaseBackend

fn eq(&self, other: &DatabaseBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
