Struct DefaultCost 

pub struct DefaultCost(pub i32, pub i32);

The default cost type used for documents.

It is composed of two values: the badness and the number of newlines. The badness quantifies how much the layout overflows the desired page width. When this cost is used, the badness will be minimized first, then the number of newlines will be minimized from there.

This cost is generally used with the DefaultCostFactory, but it is valid to use it with a custom cost factory if it serves your needs.

Tuple Fields

0: i32

The badness of the layout.

1: i32

The number of newlines the layout produced.

Trait Implementations

impl Add for DefaultCost

fn add(self, rhs: Self) -> Self::Output

Pair-wise adds the individual components of the cost.

type Output = DefaultCost

The resulting type after applying the + operator.

impl Clone for DefaultCost

fn clone(&self) -> DefaultCost

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DefaultCost

impl Cost for DefaultCost

impl Debug for DefaultCost

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

Formats the value using the given formatter.

impl Eq for DefaultCost

impl Ord for DefaultCost

fn cmp(&self, other: &DefaultCost) -> 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 DefaultCost

fn eq(&self, other: &DefaultCost) -> 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 DefaultCost

fn partial_cmp(&self, other: &DefaultCost) -> 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.
