ExecutionOutcome

Enum ExecutionOutcome

pub enum ExecutionOutcome {
    Success,
    SyntaxError,
    SemanticError,
    TypeError,
    GraphError,
    UnboundVariable,
    MissingParameter,
    Cancelled,
    Timeout,
    ResourceLimit,
}

Expand description

Coarse, stable outcome category for telemetry. Error messages and query text are deliberately excluded to avoid leaking user data through an observer by default.

Variants§

Success

SyntaxError

The query text itself never parsed — see QueryError::Syntax.

SemanticError

The query parsed but is structurally invalid, independent of any data/parameters — see QueryError::Semantic.

TypeError

A real value (from stored data or a $parameter) turned out to be the wrong shape for what the query does with it — see QueryError::Type.

GraphError

UnboundVariable

MissingParameter

Cancelled

Timeout

ResourceLimit
