Struct layout_2013::floats::Floats

pub struct Floats {
    list: FloatList,
    offset: LogicalSize<Au>,
    pub writing_mode: WritingMode,
}

Encapsulates information about floats. This is optimized to avoid allocation if there are no floats, and to avoid copying when translating the list of floats downward.

Fields

list: FloatList

The list of floats.

offset: LogicalSize<Au>

The offset of the flow relative to the first float.

writing_mode: WritingMode

The writing mode of these floats.

Implementations

impl Floats

pub fn new(writing_mode: WritingMode) -> Floats

Creates a new Floats object.

pub fn translate(&mut self, delta: LogicalSize<Au>)

Adjusts the recorded offset of the flow relative to the first float.

pub fn last_float_pos(&self) -> Option<LogicalRect<Au>>

Returns the position of the last float in flow coordinates.

pub fn available_rect( &self, block_start: Au, block_size: Au, max_x: Au, ) -> Option<LogicalRect<Au>>

Returns a rectangle that encloses the region from block-start to block-start + block-size, with inline-size small enough that it doesn’t collide with any floats. max_x is the inline-size beyond which floats have no effect. (Generally this is the containing block inline-size.)

pub fn add_float(&mut self, info: &PlacementInfo)

Adds a new float to the list.

fn max_block_size_for_bounds( &self, inline_start: Au, block_start: Au, inline_size: Au, ) -> Option<Au>

Given the three sides of the bounding rectangle in the block-start direction, finds the largest block-size that will result in the rectangle not colliding with any floats. Returns None if that block-size is infinite.

pub fn place_between_floats(&self, info: &PlacementInfo) -> LogicalRect<Au>

Given placement information, finds the closest place a fragment can be positioned without colliding with any floats.

pub fn clearance(&self, clear: ClearType) -> Au

pub fn is_present(&self) -> bool

Trait Implementations

impl Clone for Floats

fn clone(&self) -> Floats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Floats

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

Formats the value using the given formatter.
