Struct style::properties::CascadeFlags

pub struct CascadeFlags { /* fields omitted */ }

A set of flags to tweak the behavior of the cascade function.

Methods

impl CascadeFlags

pub const INHERIT_ALL: CascadeFlags

INHERIT_ALL: CascadeFlags = CascadeFlags{bits: 1,}

Whether to inherit all styles from the parent. If this flag is not present, non-inherited styles are reset to their initial values.

pub const SKIP_ROOT_AND_ITEM_BASED_DISPLAY_FIXUP: CascadeFlags

SKIP_ROOT_AND_ITEM_BASED_DISPLAY_FIXUP: CascadeFlags = CascadeFlags{bits: 1 << 1,}

Whether to skip any display style fixup for root element, flex/grid item, and ruby descendants.

pub const VISITED_DEPENDENT_ONLY: CascadeFlags

VISITED_DEPENDENT_ONLY: CascadeFlags = CascadeFlags{bits: 1 << 2,}

Whether to only cascade properties that are visited dependent.

pub const IS_ROOT_ELEMENT: CascadeFlags

IS_ROOT_ELEMENT: CascadeFlags = CascadeFlags{bits: 1 << 3,}

Whether the given element we're styling is the document element, that is, matches :root.

Not set for native anonymous content since some NAC form their own root, but share the device.

This affects some style adjustments, like blockification, and means that it may affect global state, like the Device's root font-size.

pub const PROHIBIT_DISPLAY_CONTENTS: CascadeFlags

PROHIBIT_DISPLAY_CONTENTS: CascadeFlags = CascadeFlags{bits: 1 << 4,}

Whether to convert display:contents into display:inline. This is used by Gecko to prevent display:contents on generated content.

pub const IS_FIELDSET_CONTENT: CascadeFlags

IS_FIELDSET_CONTENT: CascadeFlags = CascadeFlags{bits: 1 << 5,}

Whether we're styling the ::-moz-fieldset-content anonymous box.

pub const IS_LINK: CascadeFlags

IS_LINK: CascadeFlags = CascadeFlags{bits: 1 << 6,}

Whether we're computing the style of a link, either visited or unvisited.

pub const IS_VISITED_LINK: CascadeFlags

IS_VISITED_LINK: CascadeFlags = CascadeFlags{bits: 1 << 7,}

Whether we're computing the style of a link element that happens to be visited.

pub fn empty() -> CascadeFlags

Returns an empty set of flags.

pub fn all() -> CascadeFlags

Returns the set containing all flags.

pub fn bits(&self) -> u8

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u8) -> Option<CascadeFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u8) -> CascadeFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: CascadeFlags) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: CascadeFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: CascadeFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CascadeFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CascadeFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: CascadeFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
