[−][src]Trait httptest::mappers::Mapper

pub trait Mapper<IN>: Send + Debug where
    IN: ?Sized, {
    type Out;
    fn map(&mut self, input: &IN) -> Self::Out;
}

The core trait. Defines how an input value should be turned into an output value. This allows for a flexible pattern of composition where two or more mappers are chained together to form a readable and flexible manipulation.

There is a special case of a Mapper that outputs a bool that is called a Matcher.
