How to create a language

[Animesh Sahu]

Is there no public API to make an instance of Language? I couldn't find a way to make Language either from a raw hex or from using PrimaryLanguage and SecondaryLanguage.

rusb/src/language.rs

Lines 11 to 39 in f611e84

 #[derive(Debug, Copy, Clone, PartialEq, Eq)] 
 pub struct Language { 
     raw: u16, 
 } 
  
 impl Language { 
     /// Returns the language's 16-bit `LANGID`. 
     /// 
     /// Each language's `LANGID` is defined by the USB forum 
     /// (http://www.usb.org/developers/docs/USB_LANGIDs.pdf). 
     pub fn lang_id(self) -> u16 { 
         self.raw 
     } 
  
     /// Returns the primary language. 
     pub fn primary_language(self) -> PrimaryLanguage { 
         PrimaryLanguage::from_raw(self.raw) 
     } 
  
     /// Returns the sub language. 
     pub fn sub_language(self) -> SubLanguage { 
         SubLanguage::from_raw(self.primary_language(), self.raw) 
     } 
 } 
  
 #[doc(hidden)] 
 pub(crate) fn from_lang_id(raw: u16) -> Language { 
     Language { raw } 
 }

For what purpose you need make an instance of Language?

[Animesh Sahu]

@a1ien Reading a string descriptor from particular usb device, DeviceHandle::read_string_descriptor particularly.

You can get Language from DeviceHandle::read_languages.
