Enum DatabaseEngine 

pub enum DatabaseEngine {
    Postgres,
    MySQL,
    SQLite,
    MongoDB,
}

Supported database engines for multi-database (M14).

SQL engines (Postgres, MySQL, SQLite) use the ORM layer; MongoDB uses its own driver.

Variants

Postgres

PostgreSQL — full feature coverage.

MySQL

MySQL / MariaDB — 95% feature coverage.

SQLite

SQLite — 85% feature coverage (e.g. no full-text search like Postgres).

MongoDB

MongoDB — 75% feature coverage via mongodb crate.

Implementations

impl DatabaseEngine

pub const fn default_engine() -> Self

Default engine when not specified (single-DB backward compat).

pub const fn is_sql(&self) -> bool

Returns true for SQL backends (Postgres, MySQL, SQLite).

pub const fn is_mongo(&self) -> bool

Returns true for MongoDB.

Trait Implementations

impl Clone for DatabaseEngine

fn clone(&self) -> DatabaseEngine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseEngine

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

Formats the value using the given formatter.

impl Default for DatabaseEngine

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DatabaseEngine

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DatabaseEngine

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DatabaseEngine

fn eq(&self, other: &DatabaseEngine) -> 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 Serialize for DatabaseEngine

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for DatabaseEngine

impl Eq for DatabaseEngine

impl StructuralPartialEq for DatabaseEngine
