Extension of the UnicodeData struct provided by the ucd_parse crate. Unlike the original one, this struct does not represent a single line in the UnicodeData file, but it could be the result of a whole parsing of several files to contain range of Unicode code points. Note that this file, unlike others in the Unicode data files, represents ranges split in different lines in order not to break parsers compatibility.

Fields

codepoints: Codepoints

The code points corresponding to this row.

name: String

The name of this code point.

general_category: String

The “general category” of this code point.

canonical_combining_class: u8

The class of this code point used in the Canonical Ordering Algorithm.

Note that some classes map to a particular symbol. See UAX44, Table 15.

bidi_class: String

The bidirectional class of this code point.

Possible values are listed in UAX44, Table 13.

decomposition: UnicodeDataDecomposition

The decomposition mapping for this code point. This includes its formatting tag (if present).

numeric_type_decimal: Option<u8>

A decimal numeric representation of this code point, if it has the property Numeric_Type=Decimal.

numeric_type_digit: Option<u8>

A decimal numeric representation of this code point, if it has the property Numeric_Type=Digit. Note that while this field is still populated for existing code points, no new code points will have this field populated.

numeric_type_numeric: Option<UnicodeDataNumeric>

A decimal or rational numeric representation of this code point, if it has the property Numeric_Type=Numeric.

bidi_mirrored: bool

A Boolean indicating whether this code point is “mirrored” in bidirectional text.

unicode1_name: String

The “old” Unicode 1.0 or ISO 6429 name of this code point. Note that this field is empty unless it is significantly different from the name field.

iso_comment: String

The ISO 10464 comment field. This field no longer contains any non-NULL values.

simple_uppercase_mapping: Option<Codepoint>

This code point’s simple uppercase mapping, if it exists.

simple_lowercase_mapping: Option<Codepoint>

This code point’s simple lowercase mapping, if it exists.

simple_titlecase_mapping: Option<Codepoint>

This code point’s simple title case mapping, if it exists.

Implementations

impl UnicodeData

pub fn parse(ucd_dir: &Path) -> Result<Vec<UnicodeData>, Error>

Parse a particular UCD file into a sequence of rows.

Trait Implementations

impl Clone for UnicodeData

fn clone(&self) -> UnicodeData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnicodeData

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

Formats the value using the given formatter.

impl Default for UnicodeData

fn default() -> UnicodeData

Returns the “default value” for a type.

impl PartialEq for UnicodeData

fn eq(&self, other: &UnicodeData) -> 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 UcdLineParser<UnicodeData> for BidiClassGen

fn process_entry(&mut self, udata: &UnicodeData) -> Result<(), Error>

Process an entry in the UCD file.

impl UcdLineParser<UnicodeData> for UcdTableGen

fn process_entry(&mut self, udata: &UnicodeData) -> Result<(), Error>

Process an entry in the UCD file.

impl UcdLineParser<UnicodeData> for UnassignedTableGen

fn process_entry(&mut self, udata: &UnicodeData) -> Result<(), Error>

Process an entry in the UCD file.

impl UcdLineParser<UnicodeData> for ViramaTableGen

fn process_entry(&mut self, udata: &UnicodeData) -> Result<(), Error>

Process an entry in the UCD file.

impl UcdLineParser<UnicodeData> for WidthMappingTableGen

fn process_entry(&mut self, udata: &UnicodeData) -> Result<(), Error>

Process an entry in the UCD file.

impl Eq for UnicodeData

impl StructuralPartialEq for UnicodeData
