Trait Implementations

impl<T> StateStream for SqlStatementStream<T>

type Item = T

The items being streamed.

type State = SqlStatement

The state returned when streaming completes.

type Error = SqlError

The error returned.

fn poll(
    &mut self
) -> Poll<StreamEvent<T, SqlStatement>, (SqlError, SqlStatement)>

Similar to Stream::poll.

fn into_future(self) -> IntoFuture<Self>

Returns a future which yields the next element of the stream.

fn into_stream(self) -> IntoStream<Self>

Returns a normal Stream which yields the elements of this stream and discards the state.

fn map<F, B>(self, f: F) -> Map<Self, F> where
    F: FnMut(Self::Item) -> B, 

Returns a stream which applies a transform to items of this stream.

fn map_err<F, B>(self, f: F) -> MapErr<Self, F> where
    F: FnMut(Self::Error) -> B, 

Returns a stream which applies a transform to errors of this stream.

fn map_state<F, B>(self, f: F) -> MapState<Self, F> where
    F: FnOnce(Self::State) -> B, 

Returns a stream which applies a transform to the state of this stream.

fn filter<F>(self, f: F) -> Filter<Self, F> where
    F: FnMut(&Self::Item) -> bool, 

Returns a stream which filters items of this stream by a predicate.

fn filter_map<F, B>(self, f: F) -> FilterMap<Self, F> where
    F: FnMut(Self::Item) -> Option<B>, 

Returns a stream which filters and transforms items of this stream by a predicate.

fn collect(self) -> Collect<Self>

Returns a stream which collects all items of this stream into a Vec, returning it along with the stream's state.

fn for_each<F>(self, f: F) -> ForEach<Self, F> where
    F: FnMut(Self::Item), 

Returns a future which applies a closure to each item of this stream.
