As of Java 8, Calendar and its subclasses have been superseded by the java.time package and its subpackages. They should be preferred, unless a legacy API requires Calendar.

A CSS distance measurement is a number immediately followed by a length unit (px, em, pc, in, …) CSS supports a number of length measurements units. They are absolute or relative. valueunit 1em UnitDescription%Define sizes in terms of parent objects or current object dependent on prope...

Units at Runtime Units of Measure are used only for static checking by the compiler, and are not available at runtime. They cannot be used in reflection or in methods like ToString. For example, C# gives a double with no units for a field of type float<m> defined by and exposed from an ...

Traits are a way of describing a 'contract' that a struct must implement. Traits typically define method signatures but can also provide implementations based on other methods of the trait, providing the trait bounds allow for this. For those familiar with object oriented programming, traits can be...

implicit val x: T = ??? Implicit classes allow custom methods to be added to existing types, without having to modify their code, thereby enriching types without needing control of the code. Using implicit types to enrich an existing class is often referred to as an 'enrich my library' pat...

Starter kits enable new users to start using Emacs quickly and avoid some of the setup hurdles that come from a mature system like Emacs -- one that has grown through decades of evolution and naturally has some historical quirks. Experienced users also benefit from having a kit configuration...

AsRef and Borrow are similar but serve distinct purposes. Borrow is used to treat multiple borrowing methods similarly, or to treat borrowed values like their owned counterparts, while AsRef is used for genericizing references. From<A> for B implies Into<B> for A, but not vice-versa...

Type traits are templated constructs used to compare and test the properties of different types at compile time. They can be used to provide conditional logic at compile time that can limit or extend the functionality of your code in a specific manner. The type traits library was brought in with t...
