Enum LineBreakWordOption 

#[non_exhaustive]
pub enum LineBreakWordOption {
    Normal,
    BreakAll,
    KeepAll,
}

An enum specifies the line break opportunities between letters. It can be passed as an argument when creating a line segmenter.

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

Normal

Words break according to their customary rules. See the details in https://drafts.csswg.org/css-text-3/#valdef-word-break-normal.

BreakAll

Breaking is allowed within “words”. https://drafts.csswg.org/css-text-3/#valdef-word-break-break-all

KeepAll

Breaking is forbidden within “word”. https://drafts.csswg.org/css-text-3/#valdef-word-break-keep-all

Trait Implementations

impl Clone for LineBreakWordOption

fn clone(&self) -> LineBreakWordOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineBreakWordOption

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

Formats the value using the given formatter.

impl PartialEq for LineBreakWordOption

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
