Struct Fragmentainer 

pub struct Fragmentainer {
    pub size: LogicalSize,
    pub used_block_size: f32,
    pub is_fixed_size: bool,
    pub content: Vec<LayoutBox>,
}

A single container (fragmentainer) in a fragmentation context.

Each fragmentainer has a logical size and tracks how much of that space has been used. For continuous media, the fragmentainer can grow infinitely. For paged media, fragmentainers have fixed sizes.

Fields

size: LogicalSize

Logical size of this container (width and height)

used_block_size: f32

How much block-axis space has been used (typically vertical space)

is_fixed_size: bool

Whether this container has a fixed size (true for pages) or can grow (false for continuous)

content: Vec<LayoutBox>

Content that has been placed in this fragmentainer (populated during layout).

Implementations

impl Fragmentainer

pub fn new(size: LogicalSize, is_fixed_size: bool) -> Self

Create a new fragmentainer with the given size.

pub fn remaining_space(&self) -> f32

Get the remaining block-axis space (infinite for continuous, bounded for paged).

pub fn is_full(&self) -> bool

Check if this fragmentainer is full (less than 1px remaining).

pub fn can_fit(&self, block_size: f32) -> bool

Check if a block of the given size can fit in this fragmentainer.

pub fn use_space(&mut self, size: f32)

Record that block-axis space has been used in this fragmentainer.
