Struct QueryExecutionTrace 

pub struct QueryExecutionTrace {
    pub query_id: String,
    pub query: String,
    pub phases: Vec<QueryPhaseSpan>,
    pub total_duration_us: u64,
    pub success: bool,
    pub error: Option<String>,
    pub result_count: Option<usize>,
}

Complete trace for a query execution.

Tracks all phases from initial parse through execution, enabling performance analysis and debugging.

Fields

query_id: String

Unique query ID for tracing correlation.

query: String

Query string (truncated for large queries).

phases: Vec<QueryPhaseSpan>

List of phase spans (parse, validate, execute, etc.).

total_duration_us: u64

Total execution time in microseconds.

success: bool

Whether execution succeeded.

error: Option<String>

Optional error message.

result_count: Option<usize>

Number of results returned.

Implementations
