Enum ResponseClass 

pub enum ResponseClass {
    Completed,
    Running,
    StatementTimeout,
    StatementFailed,
    RateLimited,
    Other(u16),
}

The classification of a SQL API HTTP response by status code.

Variants

Completed

200: completed; body is a crate::response::ResultSet.

Running

202: still running / accepted async; body is a crate::response::QueryStatus. Poll again.

StatementTimeout

408: statement exceeded STATEMENT_TIMEOUT_IN_SECONDS; body is a crate::response::QueryFailureStatus. A typed timeout, not a SQL error.

StatementFailed

422: SQL compilation/execution failure; body is a crate::response::QueryFailureStatus.

RateLimited

429: server overloaded / rate limited. Back off and retry; Retry-After is not guaranteed. Never a query-status code.

Other(u16)

Any other status (e.g. 5xx transport error), carried verbatim.

Implementations

impl ResponseClass

pub const fn from_status(code: u16) -> Self

Classify a raw HTTP status code.

pub const fn should_poll(self) -> bool

Whether this state means “poll the handle again” (202 only).

pub const fn is_retryable(self) -> bool

Whether this state is transient and should be retried under backoff (429; 5xx transport). 408/422 are terminal failures, not retries.

pub const fn is_terminal(self) -> bool

Whether this state terminates the statement lifecycle (success or a typed failure). Running/RateLimited are non-terminal.

pub const fn terminal_outcome(self) -> Option<OutcomeKind>

The envelope OutcomeKind for a terminal state, or None while the statement is still in flight (Running/RateLimited/non-5xx Other).
