Enum DatabaseBackend 

#[non_exhaustive]
pub enum DatabaseBackend {
    MySql,
    Postgres,
    Sqlite,
}

The type of database backend for real world databases. This is enabled by feature flags as specified in the crate documentation

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MySql

A MySQL backend

Postgres

A PostgreSQL backend

Sqlite

A SQLite backend

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 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

pub fn as_str(&self) -> &'static str

Get the display string for this enum

Trait Implementations

impl Clone for DatabaseBackend

fn clone(&self) -> DatabaseBackend

Returns a duplicate 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

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.
