Enum icu_segmenter::line::LineBreakStrictness

#[non_exhaustive]
pub enum LineBreakStrictness {
    Loose,
    Normal,
    Strict,
    Anywhere,
}

An enum specifies the strictness of line-breaking rules. It can be passed as an argument when creating a line segmenter.

Each enum value has the same meaning with respect to the line-break property values in the CSS Text spec. See the details in https://drafts.csswg.org/css-text-3/#line-break-property.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Loose

Breaks text using the least restrictive set of line-breaking rules. Typically used for short lines, such as in newspapers. https://drafts.csswg.org/css-text-3/#valdef-line-break-loose

Normal

Breaks text using the most common set of line-breaking rules. https://drafts.csswg.org/css-text-3/#valdef-line-break-normal

Strict

Breaks text using the most stringent set of line-breaking rules. https://drafts.csswg.org/css-text-3/#valdef-line-break-strict

This is the default behaviour of the Unicode Line Breaking Algorithm, resolving class CJ to NS; see rule LB1.

Anywhere

Breaks text assuming there is a soft wrap opportunity around every typographic character unit, disregarding any prohibition against line breaks. See more details in https://drafts.csswg.org/css-text-3/#valdef-line-break-anywhere.

Trait Implementations

impl Clone for LineBreakStrictness

fn clone(&self) -> LineBreakStrictness

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LineBreakStrictness

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

Formats the value using the given formatter.

impl PartialEq for LineBreakStrictness

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