Enum CallbackRouterBuildError 

pub enum CallbackRouterBuildError {
    ReadOnlyDatabase,
    Probe(Error),
}

Reasons callback_router can refuse to build.

Variants

ReadOnlyDatabase

The database pool resolves to a read-only connection. All three callback routes mutate job state, so a read-only DB would surface as runtime 503s on every request. Fail at build time instead.

Probe(Error)

Pool probe failure when reading transaction_read_only.

Trait Implementations
