Enum DatabaseType 

pub enum DatabaseType {
    Postgres,
    MySQL,
    SQLite,
    MongoDB,
    Redis,
}

Enumeration of supported database engine types.

This enum represents the different database backends that DMSC can connect to. Each database type has specific connection requirements and may use different underlying drivers or client libraries.

Currently Implemented

Database Type	Feature Flag	Status
PostgreSQL	postgres	✅ Available
MySQL	mysql	✅ Available
SQLite	sqlite	✅ Available
MongoDB	mongodb	🔜 Planned
Redis	redis	🔜 Planned

Roadmap

MongoDB and Redis support are planned for future releases. The enum variants are reserved to maintain API stability when these features are added.

Usage

use dmsc::database::DatabaseType;

fn get_preferred_db() -> DatabaseType {
    DatabaseType::Postgres
}

Variants

MySQL is the world’s most popular open source database. It is widely used for web applications and is known for its speed and reliability. Default port is 3306.

Features

• ACID compliance (with InnoDB)
• Cross-platform support
• Stored procedures and triggers
• Full-text indexing

SQLite

SQLite database engine.

SQLite is a lightweight, file-based database engine. It requires no server and is embedded directly into the application. Suitable for development, testing, and desktop applications.

Features

• Serverless architecture
• Zero-configuration
• Single file storage
• Full SQL support

MongoDB

MongoDB database engine.

MongoDB is a document-oriented NoSQL database. It uses JSON-like documents with optional schemas. Default port is 27017.

Features

• Flexible document schema
• Horizontal scaling
• Rich query language
• Automatic sharding

Redis

Redis database engine.

Redis is an in-memory data structure store. It can be used as a database, cache, and message broker. Default port is 6379.

Features

• In-memory storage
• Data structures (strings, hashes, lists, sets)
• Pub/Sub messaging
• Persistence options

Trait Implementations

impl Clone for DatabaseType

fn clone(&self) -> DatabaseType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseType

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

Formats the value using the given formatter.

impl Default for DatabaseType

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DatabaseType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DatabaseType

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

Formats the value using the given formatter.

impl<'py> IntoPyObject<'py> for DatabaseType

type Target = DatabaseType

The Python output type

type Output = Bound<'py, <DatabaseType as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for DatabaseType

fn eq(&self, other: &DatabaseType) -> 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.

impl PyClass for DatabaseType

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for DatabaseType

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<DatabaseType>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
