StatementDurationTimeout

rivet::source

Struct StatementDurationTimeout 

Source 
pub struct StatementDurationTimeout { /* private fields */ }
Expand description

A statement-DURATION timeout that rivet itself raised — distinct from a driver-native timeout that carries a structured code (PG 57014, MySQL 3024).

The MSSQL engine has no server-side statement-duration SET, so rivet enforces tuning.statement_timeout_s client-side and raises this when the budget is exceeded (see mssql). Before this type the retry classifier’s permanence hinged on substring-matching rivet’s OWN prose (“statement timeout after …”); a reworded message would silently flip the error back to transient, and the identical query would be retried until it burned the budget N times (measured: 3×300 s = 20 min for 0 rows). Carrying a typed marker means [crate::pipeline::retry::classify_error] downcasts the TYPE, so permanence survives any change to the human-facing wording. The string branches in the classifier remain a fallback for genuinely driver-native timeout messages we do not control.
