Struct ExtendMap

pub struct ExtendMap<'extender, InputElement, ExtendElement, Mapper: FnMut(InputElement) -> ExtendElement, Extender: Extend<ExtendElement>> { /* private fields */ }

Wraps a type Extender: Extend<ExtendElement> and applies a mapping function before passing elements to the Extender.
