fn then<F, P>(self, f: F) -> Then<Self, F> where
F: FnOnce(Result<Self::Value>) -> P,
F: FnOnce(Result<Self::Value>) -> P,
Takes a closure which maps a Result<Self::Value>
to a pattern, and creates a pattern which calls that closure on the evaluation result of self
. Read more

F: FnOnce(Self::Value) -> P,
F: FnOnce(Self::Value) -> P,
Takes a closure which maps a value to a pattern, and creates a pattern which calls that closure if the evaluation of self
was succeeded. Read more
fn or_else<F, P>(self, f: F) -> OrElse<Self, F> where
F: FnOnce(Error) -> P,
F: FnOnce(Error) -> P,
Takes a closure which maps an error to a pattern, and creates a pattern which calls that closure if the evaluation of self
failed. Read more
fn map<F, T>(self, f: F) -> Map<Self, F> where
F: FnOnce(Self::Value) -> T,
F: FnOnce(Self::Value) -> T,
Takes a closure which maps a value to another value, and creates a pattern which calls that closure on the evaluated value of self
. Read more
fn chain<P>(self, other: P) -> Chain<Self, P> where

fn repeat(self) -> Repeat<Self> where
Self: Clone,
Self: Clone,
Creates Repeat
pattern to represent an infinite stream of this pattern.
