Enum ReadOnlyMode 

pub enum ReadOnlyMode {
    Auto,
    ReadOnly,
    Writable,
}

How the API server decides whether to accept mutation requests.

Auto (the default) probes the Postgres connection — useful for running the UI against a read replica or a read-only role without extra config. Forcing ReadOnly is the operator escape hatch when the DB is writable but mutations should still be disabled (e.g. an incident read-out, a shared debugging instance, a less-trusted public UI session).

Variants

Auto

Probe the DB connection — read-only if Postgres reports transaction_read_only = on, writable otherwise.

ReadOnly

Force read-only regardless of DB privilege. Mutation endpoints return 503 (the same status the auto-detect path uses) and /api/capabilities reports read_only: true.

Writable

Force writable. Mutations are always permitted at the HTTP layer; the DB still has the final say at query time.

Implementations

impl ReadOnlyMode

pub async fn resolve(self, pool: &PgPool) -> Result<bool, Error>
