Expand description

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.

Define a variable in the global scope that is an ultimate parent of this scope.

Get the Value for a variable.

Provided Methods§

Define multiple names from a value that is a list. Special case: in names is a single name, value is used directly.
