Type Alias Lang 

pub type Lang = String;

This simple type specifies that its contents contains a language identifier as defined by RFC 4646/BCP 47.

The contents of this language are interpreted based on the context of the parent XML element.

Xml example

<w:lang w:val="en-CA" />

This language is therefore specified as English (en) and Canada (CA), resulting in use of the English (Canada) language setting.

Aliased Type

pub struct Lang { /* private fields */ }
