A pointer type that uniquely owns a heap allocation of type `T`.

Trait for types that form a total order.

A trait for giving a type a useful default value.

The underline-thickness attribute represents the ideal thickness of the underline. The underline thickness is expressed in the font's coordinate system.

The `LayoutError` is returned when the parameters given to `Layout::from_size_align` or some other `Layout` constructor do not satisfy its documented constraints.

This page describes JavaScript's lexical grammar. JavaScript source text is just a sequence of characters — in order for the interpreter to understand it, the string has to be parsed to a more structured representation. The initial step of parsing is called lexical analysis, in which the text gets scanned from left to right and is converted into a sequence of individual, atomic input elements. Some input elements are insignificant to the interpreter, and will be stripped after this step — they include white space and comments. The others, including identifiers, keywords, literals, and punctuators (mostly operators), will be used for further syntax analysis. Line terminators and multiline comments are also syntactically insignificant, but they guide the process for automatic semicolons insertion to make certain invalid token sequences become valid.

The spreadMethod attribute determines how a shape is filled beyond the defined edges of a gradient.

Used to do value-to-value conversions while consuming the input value. It is the reciprocal of `Into`.

An iterator that knows its exact length.

The vector-effect property specifies the vector effect to use when drawing an object. Vector effects are applied before any of the other compositing operations, i.e., filters, masks and clips.
