Enum Dialect 

pub enum Dialect {
    Sqlite,
    Postgres {
        url: String,
    },
}

The database engine backing a test harness.

Dialect::available() is the parity entry point: a module suite loops over it so one test definition runs against every dialect the environment provides — SQLite in-memory always, Postgres 16 when FZ_TEST_POSTGRES_URL names a server (CI’s postgres:16 service container).

Variants

Sqlite

A fresh in-memory SQLite database (the default; always available).

Postgres

A throwaway database on the Postgres server at url, created when the harness builds and dropped when it drops. Requires building cratefield-testing with the postgres feature.

Fields

url: String

Implementations

impl Dialect

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

The lowercase engine name, for test-output tagging (sqlite, postgres).

pub fn postgres_url() -> Option<String>

The Postgres server URL from FZ_TEST_POSTGRES_URL (trimmed, non-empty), when the parity leg is available.

pub fn available() -> Vec<Self>

The dialects available in this environment: always SQLite; Postgres when FZ_TEST_POSTGRES_URL names a server. Prints one notice per process when the Postgres leg is unavailable, so a silently-skipped matrix leg is visible in the output.
