Enum icu_segmenter::line::LineBreakStrictness

source ·
#[non_exhaustive]
pub enum LineBreakStrictness { Loose, Normal, Strict, Anywhere, }
Expand description

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)§

This enum is marked as 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.

impl PartialEq for LineBreakStrictness

source§

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