Enum DatabaseScheme 

pub enum DatabaseScheme {
    Postgres,
    MySql,
    Sqlite,
    SqlServer,
}

Database schemes that the fraiseql-server binary can dispatch to.

The enum is exhaustive: every variant corresponds to an adapter that main() / fraiseql run know how to construct (subject to Cargo feature flags). New schemes require an explicit code change here and matching arms in build_adapter / run_once / run_watch_loop.

Variants

Postgres

postgresql:// or postgres:// — always available.

MySql

mysql:// — requires mysql Cargo feature.

Sqlite

sqlite:// — requires sqlite Cargo feature. Read-only (no SupportsMutations impl); schemas with mutations are rejected at startup.

SqlServer

sqlserver:// — requires sqlserver Cargo feature.

Implementations

impl DatabaseScheme

pub const fn required_feature(self) -> Option<&'static str>

The Cargo feature flag required to build the matching adapter into the server binary, or None for adapters that ship in the default feature set.

Trait Implementations

impl Clone for DatabaseScheme

fn clone(&self) -> DatabaseScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DatabaseScheme

impl Debug for DatabaseScheme

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

Formats the value using the given formatter.

impl Eq for DatabaseScheme

impl PartialEq for DatabaseScheme

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