Struct mysql_async::ResultSetStream

pub struct ResultSetStream<'r, 'a: 'r, 't: 'a, T, P> { /* private fields */ }

Rows stream for a single result set.

Implementations

impl<'r, 'a: 'r, 't: 'a, T, P> ResultSetStream<'r, 'a, 't, T, P>

pub fn last_insert_id(&self) -> Option<u64>

See Conn::last_insert_id.

pub fn affected_rows(&self) -> u64

See Conn::affected_rows.

pub fn info(&self) -> Cow<'_, str>

See Conn::info.

pub fn get_warnings(&self) -> u16

See Conn::get_warnings.

pub fn ok_packet(&self) -> Option<&OkPacket<'static>>

Returns an OkPacket corresponding to this result set.

Will be None if there is no OK packet (result set contains an error).

Trait Implementations

impl<'r, 'a: 'r, 't: 'a, T: Debug, P: Debug> Debug for ResultSetStream<'r, 'a, 't, T, P>

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

Formats the value using the given formatter.

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

type Item = Result<T, Error>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
