Igiciro cyo Kutaziguye muri Rust

Igiciro cyo Gukuramo: Gusobanukirwa Indirection muri Rust

Rust ni ururimi rwubakiye kumasezerano akomeye: gukuramo ibiciro bya zeru. Iyemerera abitezimbere kwandika urwego rwohejuru, umutekano, kandi rwerekana kode utishyuye ibihano byimikorere mugihe cyagenwe. Iyi filozofiya ni ishingiro ryimpamvu Rust arusha abandi gahunda ya sisitemu, kuva sisitemu y'imikorere kugeza kuri moteri y'imikino. Ariko, igitekerezo cya "indirection" cyicaye mumihanda ishimishije muburyo bwa Rust. Nubwo akenshi ari ngombwa muburyo bworoshye no guhungabanya umutekano, indirection ntabwo buri gihe iba igiciro cya zeru, kandi kuyikoresha nabi birashobora gucecekesha imikorere Rust izwi cyane. Kurubuga nka Mewayz, OS yubucuruzi busanzwe aho imikorere nogukoresha umutungo uteganijwe aribyingenzi, gusobanukirwa iki giciro ntabwo ari amasomo-ni ngombwa mukubaka ibitekerezo byubucuruzi bikomeye, binini.

Indirection ni iki kandi kuki tuyikeneye?

Indirection ni tekinike yo gutangiza gahunda aho uvuga ikintu kitari mu buryo butaziguye, ariko unyuze murwego rwo hagati. Muri Rust, imiterere isanzwe ni iyerekana, ibyerekanwe, ibintu biranga, hamwe nubwenge bwubwenge nka `Box`,` Rc`, cyangwa `Arc`. Ibi bikoresho ni ngombwa. Bashoboza imyitwarire yingirakamaro, kugabura ibirundo, kugabana nyirubwite, hamwe na polymorphism. Kurugero, `Vec >` igufasha kubika icyegeranyo cyubwoko butandukanye byose bishyira mubikorwa imiterere ya "Draw", uburyo busanzwe muri sisitemu ya UI cyangwa plugin yubatswe. Hatabayeho kwirengagiza, kwandika byoroshye, modular code byaba bigoye bidasanzwe.

"Gukuramo nubuhanga bwo guhisha ibintu bigoye, kandi indirection nigikoresho cyibanze cyayo. Muri Rust, ikibazo ni ugukoresha iki gikoresho utaretse ngo igiciro cya abstraction kibe umusoro wigihe."

Umusoro Wihishe Umusoro

Mugihe abstraction akenshi ari "zeru-igiciro" ukurikije ibyo ushobora ushobora kwandika intoki, indirection ubwayo itangiza ibintu bifatika. Iki giciro kigaragara mubice byinshi byingenzi:

• Kwibuka Kwibuka (Cache Misses): Gukurikiza icyerekezo bisaba gusimbuka kuri aderesi itandukanye. Ibi birashobora gutsinda CPU cache ibanziriza, biganisha kubisoma gahoro ugereranije ugereranije, amakuru yimbere.
• Ibi byongeweho agace gato hejuru yerekana icyerekezo kandi ikabuza abakusanya umurongo, bishobora kuba umwicanyi ukomeye wica ibintu bishyushye.

Ingamba zo Kugabanya muri Codebase yawe

Intego ntabwo ari ugukuraho indirection - ibyo ntibishoboka cyangwa byifuzwa - ahubwo ni ukubishyira mu bikorwa ubushishozi. Dore ingamba zingenzi:

Icyambere, hitamo rusange kuruta ibintu biranga aho bishoboka. Rusange ikoresha monomorphisation, ikora code itandukanye, itezimbere kuri buri bwoko bwa beto mugihe cyo gukusanya. Ibi bigumana static yoherejwe kandi igushoboza. Icya kabiri, kwakira igishushanyo mbonera-cyerekezo . Bika amakuru muburyo bujyanye, cache-yoroheje ya array (`Vec `) aho guhuza ibyegeranyo byamasanduku. Tunganya amakuru mubice, bitanyuze muminyururu yo guhamagarwa. Icya gatatu, umwirondoro udahwema . Koresha ibikoresho nka `imizigo flamegraph` kugirango umenye niba indirection ari icyuho nyacyo; kenshi, ikiguzi ni gito kugeza igihe kiri munzira ikomeye.

Mugihe utegura module ya OS ya Mewayz, abitezimbere bashishikarizwa gukoresha rusange hamwe no kohereza static kubintu byingenzi, bikora neza-nkibikorwa byo guhindura amakuru cyangwa moteri yo kubara. Hagati aho, ibintu biranga ibintu hamwe no gupakira ibintu bikomeza kuba byiza kurwego rwo hejuru, umukoresha-waguka amacomeka ya sisitemu aho guhinduka aricyo kintu cyambere gisabwa. Muguhitamo nkana kubijyanye no kwerekanwa, modul ya Mewayz irashobora gutanga ubucuruzi bukomeye abstraction ikeneye idatanze imikorere yimikorere bashingiye. Igisubizo nubucuruzi bwa moderi yubucuruzi ikora cyane kandi ikora neza, aho ikiguzi cyo gukuramo gihora ari igishoro kibizi, ntabwo ari amafaranga yihishe.

Igiciro cyo Gukuramo: Gusobanukirwa Indirection muri Rust

Rust ni ururimi rwubakiye kumasezerano akomeye: gukuramo ibiciro bya zeru. Iyemerera abitezimbere kwandika urwego rwohejuru, umutekano, kandi rwerekana kode utishyuye ibihano byimikorere mugihe cyagenwe. Iyi filozofiya ni ishingiro ryimpamvu Rust arusha abandi gahunda ya sisitemu, kuva sisitemu y'imikorere kugeza kuri moteri y'imikino. Ariko, igitekerezo cya "indirection" cyicaye mumihanda ishimishije muburyo bwa Rust. Nubwo akenshi ari ngombwa muburyo bworoshye no guhungabanya umutekano, indirection ntabwo buri gihe iba igiciro cya zeru, kandi kuyikoresha nabi birashobora gucecekesha imikorere Rust izwi cyane.
