V k\u00f3dovej b\u00e1ze syst\u00e9mov\u00e9ho mana\u017e\u00e9ra systemd sa zav\u00e1dza zmena, ktor\u00e1 umo\u017en\u00ed vytv\u00e1ranie komponentov v programovacom jazyku Rust. Rust sa pl\u00e1nuje pou\u017ei\u0165 iba na v\u00fdvoj nov\u00fdch komponentov, pri\u010dom existuj\u00faci k\u00f3d v jazyku C sa nepl\u00e1nuje prepisova\u0165 na Rust. Bal\u00ed\u010dkov\u00fd mana\u017e\u00e9r cargo sa pri zostavovan\u00ed nepou\u017e\u00edva, zost\u00e1va v platnosti iba syst\u00e9m zostavovania Meson. K\u00f3d v Ruste sa pou\u017e\u00edva v re\u017eime <no_std> (bez \u0161tandardnej kni\u017enice), povolen\u00e9 s\u00fa len kni\u017enice core, alloc a libc. <\/p>\n
Komponenty systemd v Rustu sa dynamicky prepojuj\u00fa s C-kni\u017enicou libsystemd-shared. Rust-vrstvy nad libsystemd-shared sa automaticky generuj\u00fa po\u010das zostavenia z hlavi\u010dkov\u00fdch s\u00faborov pomocou n\u00e1stroja bindgen a st\u00e1vaj\u00fa sa dostupn\u00fdmi pre rust-programy vo forme bal\u00edka systemd_shared. Na pr\u00e1cu je potrebn\u00e1 minim\u00e1lne verzia rustc 1.85 a bindgen 0.71.1, zodpovedaj\u00faca verzi\u00e1m z Debianu 13.<\/p>\n
Testovate\u013en\u00fd spustite\u013en\u00fd s\u00fabor v Rust pri zostaven\u00ed s optimaliz\u00e1ciami LTO zaber\u00e1 32 KB, zatia\u013e \u010do ekvivalent v C zaber\u00e1 20 KB. Predvolene sa podpora Rust aktivuje len v pr\u00edtomnosti zodpovedaj\u00faceho n\u00e1stroja Rust v syst\u00e9me (-Drust=auto). Ako prv\u00fd komponent, nap\u00edsan\u00fd v Rust, sa vyv\u00edja systemd-keyring-setup, ktor\u00fd zatia\u013e nebol prijat\u00fd do hlavnej k\u00f3dovej z\u00e1kladne systemd.
