Struct Filter

pub struct Filter<'a> { /* private fields */ }

The Filter function applies the Lambda to each member of the collection and returns a new collection of the same type containing only those elements for which the lambda returns true.

Providing a lambda function which does not return a Boolean results in an “invalid argument” error. If a Page is passed, its decorated fields are preserved in the result.
