Expand description

Helper to convert to/from protobuf Any message to a specific FlightSQL command message.

§Example

let flightsql_message = CommandStatementQuery {
  query: "SELECT * FROM foo".to_string(),
  transaction_id: None,
};

// Given a packed FlightSQL Any message
let any_message = Any::pack(&flightsql_message).unwrap();

// decode it to Command:
match Command::try_from(any_message).unwrap() {
  Command::CommandStatementQuery(decoded) => {
   assert_eq!(flightsql_message, decoded);
  }
  _ => panic!("Unexpected decoded message"),
}

Implementations§

impl Command

pub fn into_any(self) -> Any

Convert the command to Any.

pub fn type_url(&self) -> &str

Get the URL for the command.

Trait Implementations§

impl Clone for Command

fn clone(&self) -> Command

Returns a copy of the value. Read more

1.0.0 · source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more

impl Debug for Command

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

This method tests for self and other values to be equal, and is used by ==.

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
