Struct handy_io::pattern::combinators::Chain
[−]
[src]
pub struct Chain<P0, P1>(_, _);
A pattern for the chain
combinator,
chaining values of the two pattern P0
and P1
as a tuple value.
This pattern is created by calling Pattern::chain
method.

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

was succeeded. Read more
