Module style::properties::cascade

The main cascading algorithm of the style system.

Structs

• Cascade 🔒
• Declaration 🔒
• DeclarationIterator 🔒
• Declarations 🔒
  The set of property declarations from our rules.
• PrioritaryDeclarationPosition 🔒
  “Prioritary” properties are properties that other properties depend on in one way or another.

Enums

• CascadeMode
  Whether we’re cascading for visited or unvisited styles.
• FirstLineReparenting
  Whether we’re resolving a style with the purposes of reparenting for ::first-line.

Functions

• apply_declarations
  NOTE: This function expects the declaration with more priority to appear first.
• cascade
  Performs the CSS cascade, computing new styles for an element from its parent style.
• cascade_rules 🔒
• iter_declarations 🔒
• tweak_when_ignoring_colors 🔒

Type Aliases

• DeclarationIndex 🔒
  We track the index only for prioritary properties. For other properties we can just iterate.
• DeclarationsToApplyUnlessOverriden 🔒
  For ignored colors mode, we sometimes want to do something equivalent to “revert-or-initial”, where we revert for a given origin, but then apply a given initial value if nothing in other origins did override it.
