    WithoutBlock(R),

The return value for AtRuleParser::parse_prelude. Indicates whether the at-rule is expected to have a { /* ... */ } block or end with a ; semicolon.

Variants

WithoutBlock(R)

The at-rule is expected to end with a ; semicolon. Example: @import.

The value is the finished representation of an at-rule as returned by RuleListParser::next or DeclarationListParser::next.

WithBlock(P)

The at-rule is expected to have a a { /* ... */ } block. Example: @media

The value is the representation of the "prelude" part of the rule.

OptionalBlock(P)

The at-rule may either have a block or end with a semicolon.

This is mostly for testing. As of this writing no real CSS at-rule behaves like this.

The value is the representation of the "prelude" part of the rule.
