Nu herexporteert std deze delen. <a rel=\"nofollow\" href=\"https:\/\/blog.rust-lang.org\/2019\/07\/04\/Rust-1.36.0.html#the-alloc-crate-is-stable\">Meer hierover<\/a>.\n    <\/li>\n<li>MaybeUninit in plaats van mem::uninitialized.<br \/> In eerdere releases stelde mem::uninitialized je in staat om de initi\u00eble controle te omzeilen; dit werd gebruikt voor luie allocatie van arrays, maar deze functie is behoorlijk riskant (<a rel=\"nofollow\" href=\"https:\/\/blog.rust-lang.org\/2019\/07\/04\/Rust-1.36.0.html#maybeuninitt%3E-instead-of-mem::uninitialized\">meer informatie<\/a>), daarom is het type MaybeUninit gestabiliseerd, wat veiliger is. <br \/> En omdat MaybeUninit een veiligere vervanging is, zal mem::uninitialized vanaf Rust 1.38 een verouderde functie zijn. <br \/> Als je meer wilt weten over niet-ge\u00efnitialiseerd geheugen, kun je de blogpost (Alexis Beingessner) lezen.\n   <\/li>\n<li> NLL voor Rust 2015. <br \/> In de aankondiging van <a rel=\"nofollow\" href=\"https:\/\/blog.rust-lang.org\/2018\/12\/06\/Rust-1.31-and-rust-2018.html#non-lexical-lifetimes\">Rust 1.31.0<\/a> vertelden de ontwikkelaars ons over NLL (Non-Lexical Lifetime), een verbetering voor de taal die de borrow checker slimmer en gebruiksvriendelijker maakt. Voorbeeld:<br \/>\nfn main() {<br \/>\n    let mut x = 5;<br \/>\n    let y = &amp;x;<br \/>\n    let z = &amp;mut x; \/\/ Dit was niet toegestaan voor 1.31.0.<br \/>\n}<\/p>\n<p>In 1.31.0 werkte NLL alleen in Rust 2018, met de belofte dat de ontwikkelaars ondersteuning zouden toevoegen voor Rust 2015. <br \/> Als je meer wilt weten over NLL, kun je daar meer over lezen in deze <a rel=\"nofollow\" href=\"http:\/\/blog.pnkfx.org\/blog\/2019\/06\/26\/breaking-news-non-lexical-lifetimes-arrives-for-everyone\/\"> blogpost<\/a> (Felix Klocks).\n    <\/li>\n<li>Nieuwe vlag voor Cargo &#8212; &#8212;offline.<br \/>In Rust 1.36 is een nieuwe vlag voor Cargo gestabiliseerd. De vlag &#8212;offline zorgt ervoor dat Cargo lokale gecacheerde afhankelijkheden gebruikt, zodat deze later zonder internet kunnen worden gebruikt. Wanneer de benodigde afhankelijkheden offline niet beschikbaar zijn, en als internet toch nodig is, zal Cargo een foutmelding geven. Om afhankelijkheden van tevoren te downloaden, kan de opdracht cargo fetch worden gebruikt, die alle afhankelijkheden zal downloaden.\n    <\/li>\n<li><a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/cargo\/blob\/master\/CHANGELOG.md#cargo-136-2019-07-04\">Hier<\/a> je kunt een gedetailleerd overzicht van de veranderingen lezen.\n<\/li>\n<\/ul>\n<p>\nEr zijn ook veranderingen in de standaardbibliotheek:\n<\/p>\n<ul>\n<li> De macro dbg!() kan nu meerdere argumenten aannemen.\n    <\/li>\n<li> Een aantal API's zijn nu gemarkeerd als const:\n<ul>\n<li><a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/core\/alloc\/struct.Layout.html#method.from_size_align_unchecked\">Layout::from_size_align_unchecked<\/a>;\n        <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/mem\/fn.needs_drop.html\">mem::needs_drop<\/a>;\n        <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/ptr\/struct.NonNull.html#method.dangling\">NonNull::dangling<\/a>;\n        <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/ptr\/struct.NonNull.html#method.cast\">NonNull::cast<\/a>.\n        <\/li>\n<\/ul>\n<\/li>\n<li>Nieuwe API's die zijn gestabiliseerd:\n<ul>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/task\/struct.Waker.html\">task::Waker<\/a> en <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/task\/enum.Poll.html\">task::Poll<\/a>;\n        <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/collections\/struct.VecDeque.html#method.rotate_left\"> VecDeque::rotate_left<\/a> en <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/collections\/struct.VecDeque.html#method.rotate_right\">VecDeque::rotate_right<\/a>;\n       <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/io\/trait.Read.html#method.read_vectored\">Read::read_vectored<\/a> en <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/io\/trait.Write.html#method.write_vectored\">Write::write_vectored<\/a>;\n       <\/li>\n<li> <a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/iter\/trait.Iterator.html#method.copied\">Iterator::copied<\/a>;\n       <\/li>\n<li><a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/rust\/pull\/60404\">BorrowMut voor String<\/a>;\n       <\/li>\n<li><a rel=\"nofollow\" href=\"https:\/\/doc.rust-lang.org\/std\/primitive.str.html#method.as_mut_ptr\">str::as_mut_ptr<\/a>.\n       <\/li>\n<\/ul>\n<\/li>\n<li> Andere wijzigingen in de standaardbibliotheek vindt u hier. <a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/rust\/blob\/master\/RELEASES.md#version-1360-2019-07-04\">hier<\/a>.\n<\/li>\n<\/ul>\n<p>\nAndere veranderingen <a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/rust\/blob\/master\/RELEASES.md#version-1360-2019-07-04\">Rust<\/a>, <a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/cargo\/blob\/master\/CHANGELOG.md#cargo-136-2019-07-04\">Cargo<\/a> en <a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-lang\/rust-clippy\/blob\/master\/CHANGELOG.md#rust-136\">Clippy<\/a>.\n<\/p>\n<p>Bron: <a \ncontent=\"nofollow\" rel=\"nofollow\" href=\"http:\/\/www.linux.org.ru\/news\/development\/15090750\">linux.org.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u0430\u043d\u0434\u0430 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u043e\u0432 \u0441 \u0440\u0430\u0434\u043e\u0441\u0442\u044c\u044e \u043f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u044f\u0435\u0442 \u0432\u0430\u043c Rust 1.36! \u0427\u0442\u043e \u043d\u043e\u0432\u043e\u0433\u043e \u0432 Rust 1.36?
