Summary:

No explicit reason for the name is given. However, it is incredibly likely the name comes from the world of parsers, where one "expects" to see a particular token (else the compilation fails).

Within rustc, the use of expect-like functions long predate use within Option. These are functions like expect(p, token::SEMI) to expect to parse a semicolon and expect_word(p, "let") to expect to parse the let keyword. If the expectation isn't met, compilation fails with an error message.

Eventually a utility function was added within the compiler that would expect not a specific token or string, but that a given Option contained a value (else, fail compilation with the given error message). Over time this was moved to the Option struct itself, where it remains today.

Personally, I don't find it unusual at all. It's just another verb you can do to the object, like unwrapping or taking or mapping its value. Expecting a value (else, fail) from your Option seems quite natural.

The history about putting words together using casing goes back a long time.

From Capitalize My Title:

CamelCase was primarily used in chemistry as a way to notate chemical compounds and formulas. In 1813, Berzelius, a Swedish chemist, suggested that the chemical elements should be represented consisting of one or two letters with the first one capitalized. The term used for this convention was medical capitals.

A step into the twentieth century:

In the early twentieth century, medical capitals used in Chemistry has been adopted in product trademarks and corporate names. However, the use is not yet prevalent. Some examples of these products include DryIce Corporation, CinemaScope, a widescreen movie format, MisterRogers, and VistaVision, among others.

And in programming language:

Around the 1970s and 1980s, the use of medical capitals was also adopted as an alternative naming convention for identifiers in various programming languages. For instance, on the General Purpose Macro Processor (GPM) by Christopher Strachey, a program includes identifiers using medical capitals. These include “WriteSymbol,” and “NextCh.”

Late 1990s:

By the late 1990s, the lower camel case became a popular trend in many brands. The lowercase for “i” which may stand for internet, information, or intelligent, and “e” which stands for electronic, became prefixes to various words. Examples of these words include eBay, iMac, eBox, and iPod.

The name CamelCase:

The term CamelCase only came into existence in the 1990s. Before that, the term medical capitals was commonly used. In April 1990, the term “InterCaps” was used by Avi Rappoport to describe the manner of capitalization. In 1991, Eric S. Raymond made mention of BiCapitalization to identify it.

It was not until 1995, however, that its current name was used. In a post by Newton Love, he mentioned that the humpiness of the style made him call it HumpyCase at first, before settling with CamelCase.

The origin of the name PascalCasing (from History around Pascal Casing and Camel Casing):

In the initial design of the Framework we had hundreds of hours of debate about naming style. To facilitate these debates we coined a number of terms. With Anders Heilsberg (the original designer of Turbo Pascal) a key member of the design team, it is no wonder that we chose the term Pascal Casing for the casing style popularized by the Pascal programming language.

We were somewhat cute in using the term camelCasing for the casing style that looks something like the hump on a camel. We used the term SCREAMING CAPS to indicate an all upper case style. Luckily this style (and name) did not survive in the final guideline.

TL;DR: It's just a simple ref-counted container for a variable-length blob of binary data used by the D3DCompiler COM interfaces.

The HLSL compiler produces a 'shader blob' which is just an opaque binary object. It has a size and data. It could be really anything, but in the world of "COM" objects, it was implemented for Windows Vista as ID3D10Blob with the introduction of Direct3D 10.

Historically, Direct3D 9 and earlier had a 'fixed-function' rendering pipeline which means you could use it without HLSL shaders. For Direct3D 10, the 'fixed-function' was removed, so HLSL was required to use it at all. Therefore, a version of the Direct3D HLSL Compiler was added to the OS.

The ID3DBlob interface is what's used for Direct3D 11 or Direct3D 12, but if you look at it closely, it's the same thing.

As it turns out, my WordDetails.class was wrong. All the variables had to be in the form of list.

From ?ifelse

ifelse returns a value with the same shape as test

Rather than converting the titles iterable to a list, you can iterate over them and take the text element using the text attribute on the tag:
