Module custom_properties

Expand description

Macros§

ComputedCustomProperties: A pair of separate CustomPropertiesMaps, split between custom properties that have the inherit flag set and those with the flag unset.
CssEnvironment: The environment from which to get env function values.
CustomPropertiesBuilder: A struct that takes care of encapsulating the cascade process for custom properties.
EnvironmentVariable 🔒
NonCustomReferenceMap 🔒
NonCustomReferences 🔒: Set of flags to non-custom references this custom property makes.
References 🔒: A struct holding information about the external references to that a custom property value may have.
Substitution 🔒
VarOrEnvReference 🔒
VariableFallback 🔒
VariableValue: A value for a custom property is just a set of tokens.

DeferFontRelativeCustomPropertyResolution: Whether to defer resolving custom properties referencing font relative units.
SingleNonCustomReference 🔒

compute_value 🔒
compute_variable_value: Given a potentially registered variable value turn it into a computed custom property value.
do_substitute_chunk 🔒
eval_gtk_csd_titlebar_radius 🔒
find_non_custom_references 🔒
get_content_preferred_color_scheme 🔒
get_hairline 🔒
get_safearea_inset_bottom 🔒
get_safearea_inset_left 🔒
get_safearea_inset_right 🔒
get_safearea_inset_top 🔒
get_scrollbar_inline_size 🔒
handle_invalid_at_computed_value_time 🔒
parse_declaration_value 🔒: https://drafts.csswg.org/css-syntax-3/#typedef-declaration-value
parse_declaration_value_block 🔒: Like parse_declaration_value, but accept ! and ; since they are only invalid at the top level.
parse_name: Parse a custom property name.
remove_and_insert_initial_value 🔒: Removes the named registered custom property and inserts its uncomputed initial value.
substitute: Replace var() and env() functions, returning the resulting CSS string.
substitute_all 🔒: Resolve all custom properties to either substituted, invalid, or unset (meaning we should use the inherited value).
substitute_internal 🔒: Replace var() and env() functions. Return Err(..) for invalid at computed time.
substitute_one_reference 🔒
substitute_references_if_needed_and_apply 🔒: Replace var() and env() functions in a pre-existing variable value.

ComputedValue: Both specified and computed values are VariableValues, the difference is whether var() functions are expanded.
EnvironmentEvaluator 🔒
Name: A custom property name is just an Atom.
SpecifiedValue: Both specified and computed values are VariableValues, the difference is whether var() functions are expanded.
