[−][src]Module casco::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.

Error	Type of error that is returned during validation.
Item	Represents a CSS item: either a property or a rule.

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.
