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. Supports direct-SQL Insert/Delete mutations; Update and custom / stored-procedure mutations are rejected at startup (see guard_sqlite_mutations).

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.
