pub async fn execute_command(

    statements: Vec<String>,
    identity: Identity,
    params: Params,
    timeout: Duration,
) -> ExecuteResult<Vec<Frame>>

Execute a command on the blocking thread pool with timeout.

Commands are write operations (INSERT, UPDATE, DELETE, DDL) that modify the database state.

Arguments

• engine - The database engine to execute the command on
• statements - The RQL command statements
• identity - The identity context for permission checking
• params - Command parameters
• timeout - Maximum time to wait for command completion

Returns

• Ok(Vec<Frame>) - Command results on success
• Err(ExecuteError::Timeout) - If the command exceeds the timeout
• Err(ExecuteError::TaskPanic) - If the blocking task panics
• Err(ExecuteError::Engine) - If the engine returns an error
