Variables, functions and mixins are defined in a Scope.

A scope can be a local scope, e.g. in a function, or the global scope. All scopes except the global scope has a parent. The global scope is global to a sass document, multiple different global scopes may exists in the same rust-language process.

Required Methods

Define a variable with a value.

The $ sign is not included in name.
