Struct Fragmentation 

pub struct Fragmentation {
    pub orphans: u8,
    pub widows: u8,
}

Lines a split text block keeps on either side of a page break.

Fields

orphans: u8

Lines that must stay before a break.

widows: u8

Lines that must follow a break.

Implementations

impl Fragmentation

pub const ANYWHERE: Fragmentation

Breaks between any two lines.

pub fn lines_on_page( self, total: usize, first: usize, available: usize, ) -> usize

How many lines of a block of total, continuing at first, go on a page with room for available more: all that remain when they fit, otherwise as many as fit while leaving widows for the next page, or none when fewer than orphans would stay.

Trait Implementations

impl Clone for Fragmentation

fn clone(&self) -> Fragmentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fragmentation

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

Formats the value using the given formatter.

impl Default for Fragmentation

fn default() -> Fragmentation

Returns the “default value” for a type.

impl Hash for Fragmentation

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

where __H: Hasher,

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 PartialEq for Fragmentation

fn eq(&self, other: &Fragmentation) -> 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.
