so, there's struct looks this: struct foo { alpha: vec<t>, beta: vec<t>, } and method should move values matches condition alpha beta . question is: clean way without owning self ? the vec::partition() method can't used because moving of self.alpha causes cannot move out of dereference of &mut-pointer compile error. ps: t have file inside doesn't implement clone . do want drop beta ? sort of thing std::mem::replace for, allowing pull out: use std::mem; impl foo { fn munge(&mut self) { let alpha = mem::replace(&mut self.alpha, vec::new()); let (alpha, beta) = alpha.partition(…); self.alpha = alpha; self.beta = beta; } } note there is new vec created there briefly, doesn’t matter; doesn’t involve allocation , cheap. (the alternative leaving uninitialised memory there , replacing again, forgetting uninitialised memory, unsafe if partition can fail run destructor on uninit...

i using spell checker in android app. if is off in language , input settings app crashes. needs on app work properly. is there way before using can place check verify spell checker on or turn on directly code? you can check instance of spellcheckersession null , accordingly decide whether spellchecker turned on or not: code snippet: final textservicesmanager tsm = (textservicesmanager) getsystemservice(context.text_services_manager_service); scs = tsm.newspellcheckersession(null, null, this, true); if (scs != null) { scs.getsuggestions(new textinfo(text.gettext().tostring()), 3); } else { // show message user toast.maketext(this, "please turn on spell checker setting", toast.length_long).show(); // can open settings page user turn on componentname componenttolaunch = new componentname("com.android.settings", "com.android.settings.settings$spellcheckerssettingsactivity"); intent intent = new in...

i don't know if possible bottle. website (powered bottle) allow users upload image files. limited size of 100k. use following code in web server that. uploadlimit = 100 # 100k uploadlimitinbyte = uploadlimit* 2**10 print("before call request.headers.get('content-length')") contentlen = request.headers.get('content-length') if contentlen: contentlen = int(contentlen) if contentlen > uploadlimitinbyte: return httpresponse('upload limit 100k') but when clicked upload button in web browser upload file size 2mb, seems server receiving whole 2mb http request. expect above code receive http headers instead of receiving whole http request. not prevent wasting time on receving unecessary bytes

package test; public class test { public static void main(string[] args) { char b=65; char b='\u0041'; //aren't these same? } } probably because native character set java programming language unicode , english not language in world. programs written using unicode character set. © jls §3.1 in compiled java program char b = 65 , char b = '\u0041' produce absolutely equivalent bytecode. unicode escape sequence (\uxxxx) can used anywhere in source code, not in string or character literal definition, while number representation not. short example: public class helloworld { public static void \u006d\u0061\u0069\u006e(string[] args) { system.out.println("hello, world!"); } } this absolutely correct "hello world" program main(string[] args) method. further reading: jls §3.2
