Struct LanguagePreferences 

pub struct LanguagePreferences { /* private fields */ }

Language preferences for a user

Returned from lang_prefs()

Fields are sorted in order of the user’s preference.

POSIX locale values and GNU nonstandard categories are defined in https://man7.org/linux/man-pages/man7/locale.7.html. Windows locale values are defined in https://learn.microsoft.com/en-us/cpp/c-runtime-library/locale-categories.

Implementations

impl LanguagePreferences

pub fn collation_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the collation langs of this LanguagePreferences in order of the user’s preference

Collation langs are used for sorting and regular expressions, including character equivalence classes and multicharacter collating elements.

pub fn char_class_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the char class langs of this LanguagePreferences in order of the user’s preference

Char class langs determine the interpretation of byte sequences as characters (e.g., single versus multibyte characters), character classifications (e.g., alphabetic or digit), and the behavior of character classes.

pub fn monetary_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the monetary langs of this LanguagePreferences in order of the user’s preference

Monetary langs determine the formatting used for monetary-related numeric values, i.e, the way numbers are usually printed with details such as decimal point versus decimal comma.

For nonmonetary numeric values, see LanguagePreferences::numeric_langs

pub fn message_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the messages langs of this LanguagePreferences in order of the user’s preference

Message determines the language in which messages are displayed and what an affirmative or negative answer looks like.

pub fn numeric_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the numeric langs of this LanguagePreferences in order of the user’s preference

Numeric langs determine the formatting rules used for nonmonetary numeric values. For example, the thousands separator and the radix character.

For monetary formatting, see LanguagePreferences::monetary_langs.

pub fn time_langs(&self) -> impl Iterator<Item = Language> + '_

Returns the time langs of this LanguagePreferences in order of the user’s preference

Time langs determine format and contents of date and time information.
