Variants§
LeftToRight
Any strong left-to-right character.

ArabicLetter
Any strong right-to-left (Arabic-type) character.
EuropeanNumber
Any ASCII digit or Eastern Arabic-Indic digit.
EuropeanSeparator

EuropeanTerminator
A terminator in a numeric format context, includes currency signs.
ArabicNumber
Any Arabic-Indic digit.
CommonSeparator
Commas, colons, and slashes.
NonSpacingMark
Any non-spacing mark.
BoundaryNeutral
Most format characters, control codes, or non-characters.
Emoji
Emoji chars, components and zero-width-joiner between emoji.
LineBreak
Various newline characters.
Tab
A sequence of '\t', '\v'
or '\u{1F}'
.
Space

OtherNeutral
Most other symbols and punctuation marks.
Bracket(char)
Open or close bidi bracket.
Can be any chars in https://unicode.org/Public/UNIDATA/BidiBrackets.txt.
BidiCtrl(char)
Bidi control character.
Chars can be:
-
\u{202A}
: The LR embedding control. -
\u{202D}
: The LR override control. -
\u{202B}
: The RL embedding control. -
\u{202E}
: The RL override control. -
\u{202C}
: Terminates an embedding or override control. -
\u{2066}
: The LR isolate control. -
\u{2067}
: The RL isolate control. -
\u{2068}
: The first strong isolate control. -
\u{2069}
: Terminates an isolate control.
Implementations§
source§impl TextSegmentKind
impl TextSegmentKind
sourcepub fn is_word(self) -> bool
pub fn is_word(self) -> bool
Returns true
if the segment can be considered part of a word for the purpose of inserting letter spacing.
sourcepub fn is_space(self) -> bool
pub fn is_space(self) -> bool
Returns true
if the segment can be considered part of space between words for the purpose of inserting word spacing.
sourcepub fn is_line_break(self) -> bool
pub fn is_line_break(self) -> bool
Returns true
if the segment terminates the current line.
Line break segments are the last segment of their line and explicitly start a new line.
sourcepub fn can_merge(self) -> bool
pub fn can_merge(self) -> bool
If multiple segments of this same kind can be represented by a single segment in the Unicode bidi algorithm.
sourcepub fn bracket_info(self) -> Option<BidiMatchedOpeningBracket>
pub fn bracket_info(self) -> Option<BidiMatchedOpeningBracket>
Get more info about the bracket char if self
is Bracket(_)
with a valid char.
sourcepub fn strong_direction(self) -> Option<LayoutDirection>
pub fn strong_direction(self) -> Option<LayoutDirection>
Gets the layout direction this segment will always be in, independent of the base direction.
Returns None
if the segment direction depends on the line context.
