Module cascade 

Types and functions to parse a token stream into a cascade.

Structs

Property

Represents a CSS property that starts with a sequence of tokens which usually is the name, a colon, another sequence of tokens which usually is the value and finally ends with a semicolon. The semicolon is the parser’s anchor point: it starts by locating the semicolon and then parses backwards until it has collected the name.

Rule

Represents a CSS rule that starts with a preamble which usually contains the selectors and ends with a { ... } delimited group.

Enums

Error

Type of error that is returned during validation.

Item

Represents a CSS item: either a property or a rule.

Functions

parse

Parses the given token stream and returns a vector of items. These items might be missing fields. Use validate(items) to check for any errors. In addition, this function does not recursively parse rules.

parse_property

Parses a single property and zero or more preceeding rules from the given slice of tokens.

parse_rules

Parses zero or more rules from the given slice of tokens.

validate

Validates the given parse and returns any errors that it encounters.
