Trait Implementations

impl Future for TxtLookupFuture

type Item = TxtLookup

The type of value that this future will resolved with if it is successful.

type Error = ResolveError

The type of error that this future will resolve with if it fails in a normal fashion.

fn poll(&mut self) -> Poll<Self::Item, Self::Error>

Query this future to see if its value has become available, registering interest if it is not.

fn wait(self) -> Result<Self::Item, Self::Error>

Block the current thread until this future is resolved.

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

Map this future's result to a different type, returning a new future of the resulting type.

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

Map this future's error to a different error, returning a new future.

fn from_err<E>(self) -> FromErr<Self, E> where     E: From<Self::Error>,

Map this future's error to any error implementing From for this future's Error, returning a new future.

fn then<F, B>(self, f: F) -> Then<Self, B, F> where     B: IntoFuture,     F: FnOnce(Result<Self::Item, Self::Error>) -> B,

Chain on a computation for when a future finished, passing the result of the future to the provided closure f.

fn and_then<F, B>(self, f: F) -> AndThen<Self, B, F> where     B: IntoFuture<Error = Self::Error>,     F: FnOnce(Self::Item) -> B,

Execute another future after this one has resolved successfully.

fn or_else<F, B>(self, f: F) -> OrElse<Self, B, F> where     B: IntoFuture<Item = Self::Item>,     F: FnOnce(Self::Error) -> B,

Execute another future if this one resolves with an error.

fn select<B>(self, other: B) -> Select<Self, <B as IntoFuture>::Future> where     B: IntoFuture<Item = Self::Item, Error = Self::Error>,

Waits for either one of two futures to complete.

fn select2<B>(self, other: B) -> Select2<Self, <B as IntoFuture>::Future> where     B: IntoFuture,

Waits for either one of two differently-typed futures to complete.

fn join<B>(self, other: B) -> Join<Self, <B as IntoFuture>::Future> where     B: IntoFuture<Error = Self::Error>,

Joins the result of two futures, waiting for them both to complete.

fn join3<B, C>(     self,     b: B,     c: C ) -> Join3<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future> where     B: IntoFuture<Error = Self::Error>,     C: IntoFuture<Error = Self::Error>,

Same as join, but with more futures.

fn join4<B, C, D>(     self,     b: B,     c: C,     d: D ) -> Join4<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future, <D as IntoFuture>::Future> where     B: IntoFuture<Error = Self::Error>,     C: IntoFuture<Error = Self::Error>,     D: IntoFuture<Error = Self::Error>,

Same as join, but with more futures.

fn join5<B, C, D, E>(     self,     b: B,     c: C,     d: D,     e: E ) -> Join5<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future, <D as IntoFuture>::Future, <E as IntoFuture>::Future> where     B: IntoFuture<Error = Self::Error>,     C: IntoFuture<Error = Self::Error>,     D: IntoFuture<Error = Self::Error>,     E: IntoFuture<Error = Self::Error>,

Same as join, but with more futures.

fn into_stream(self) -> IntoStream<Self>

Convert this future into a single element stream.

fn flatten(self) -> Flatten<Self> where     Self::Item: IntoFuture,     <Self::Item as IntoFuture>::Error: From<Self::Error>,

Flatten the execution of this future when the successful result of this future is itself another future.

fn flatten_stream(self) -> FlattenStream<Self> where     Self::Item: Stream,     <Self::Item as Stream>::Error == Self::Error,

Flatten the execution of this future when the successful result of this future is a stream.

fn fuse(self) -> Fuse<Self>

Fuse a future such that poll will never again be called once it has completed.

fn inspect<F>(self, f: F) -> Inspect<Self, F> where     F: FnOnce(&Self::Item),

Do something with the item of a future, passing it on.

fn catch_unwind(self) -> CatchUnwind<Self> where     Self: UnwindSafe,

Catches unwinding panics while polling the future.

fn shared(self) -> Shared<Self>

Create a cloneable handle to this future where all handles will resolve to the same result.
