Struct handy_async::pattern::BoxPattern

pub struct BoxPattern<M: Matcher, T>(_);

Boxed pattern.

Trait Implementations

impl<M: Matcher, T> Pattern for BoxPattern<M, T>

type Value = T

The value type associated to the pattern.

fn then<F, P, E>(self, f: F) -> Then<Self, F, E> where F: FnOnce(Result<Self::Value, E>) -> 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.

fn and_then<F, P>(self, f: F) -> AndThen<Self, F> where 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.

fn or_else<F, P, E>(self, f: F) -> OrElse<Self, F, E> where F: FnOnce(E) -> 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.

fn or<P>(self, other: P) -> Or<Self, P> where P: Pattern<Value=Self::Value>

Takes a pattern other which will be used if the evaluation of self is failed.

fn map<F, T>(self, f: F) -> Map<Self, F> where 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.

fn chain<P>(self, other: P) -> Chain<Self, P> where P: Pattern

Takes two patterns and creates a new pattern over both in sequence.

fn repeat(self) -> Repeat<Self> where Self: Clone

Creates Repeat pattern to represent an infinite stream of this pattern.

fn expect_eq(self, expected_value: Self::Value) -> Expect<Self> where Self::Value: PartialEq

Takes an expected value and creates a pattern which performs a pattern matching and validates that the matched value is equal to the expected one.

fn boxed<M: Matcher>(self) -> BoxPattern<M, Self::Value> where Self: AsyncMatch<M> + 'static, Self::Future: Send + 'static

Returnes a boxed pattern to match with a matcher M.

impl<M: Matcher, T> AsyncMatch<M> for BoxPattern<M, T>

type Future = BoxFuture<(M, T), AsyncError<M, M::Error>>

The future type which will produce a value Self::Value by matching this pattern and a matcher M.

fn async_match(self, matcher: M) -> Self::Future

Creates a future which will produce a Self::Value by matching this pattern and the matcher.

fn into_stream(self, matcher: M) -> MatchStream<M, Self> where Self: Clone

Consumes this pattern and the matcher, returning a stream which will produce a sequence of matched values.
