Struct IfcId 

pub struct IfcId(pub u32);

Unique identifier for an Inline Formatting Context (IFC).

An IFC represents a region where inline content (text, inline-blocks, images) is laid out together. One IFC can contain content from multiple DOM nodes (e.g., <p>Hello <span>world</span>!</p> is one IFC with 3 text runs).

The ID is generated using a global atomic counter that resets at the start of each layout pass. This ensures:

• IDs are unique within a layout pass
• The same logical IFC gets the same ID across frames (for selection stability)

Tuple Fields

0: u32

Implementations

impl IfcId

pub fn unique() -> Self

Generate a new unique IFC ID.

pub fn reset_counter()

Reset the IFC ID counter. Called at the start of each layout pass.

Trait Implementations

impl Clone for IfcId

fn clone(&self) -> IfcId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IfcId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for IfcId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IfcId

fn cmp(&self, other: &IfcId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IfcId

fn eq(&self, other: &IfcId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for IfcId

fn partial_cmp(&self, other: &IfcId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
