Kev tso tawm ntawm Rust 1.67 cov lus qhia dav dav, tsim los ntawm Mozilla qhov project, tab sis tam sim no tsim los ntawm kev txhawb nqa ntawm lub koom haum ywj pheej tsis muaj txiaj ntsig Rust Foundation, tau tshaj tawm. Cov lus qhia txog kev nyab xeeb ntawm kev nco thiab muab txoj hauv kev kom ua tiav txoj haujlwm siab sib luag thaum tsis txhob siv cov khoom siv khib nyiab thiab lub sijhawm ua haujlwm (runtime raug txo qis rau kev pib pib thiab kev saib xyuas ntawm lub tsev qiv ntawv txheem).
Rust lub cim xeeb tuav txoj kev cawm tus tsim tawm los ntawm kev ua yuam kev thaum tswj cov taw qhia thiab tiv thaiv cov teeb meem uas tshwm sim los ntawm kev ua haujlwm qis qis, xws li nkag mus rau thaj chaw nco tom qab nws tau tso tawm, dereferencing null pointers, tsis overruns, thiab lwm yam. Txhawm rau faib cov tsev qiv ntawv, muab kev tsim kho thiab tswj hwm kev vam khom, qhov project tsim tus thawj tswj hwm pob khoom. Lub crates.io repository yog txaus siab rau hosting cov tsev qiv ntawv.
Kev nyab xeeb nco yog muab rau hauv Rust ntawm lub sijhawm sau los ntawm kev siv tshuaj xyuas, ua raws li cov tswv cuab ntawm cov khoom, khaws cov khoom siv lub neej (scopes), thiab ntsuas qhov tseeb ntawm kev nkag mus rau lub cim xeeb thaum lub sijhawm ua tiav cov lej. Rust kuj tseem muab kev tiv thaiv tus lej ntau dhau, yuav tsum muaj qhov sib txawv kom pib ua ntej siv, ua haujlwm yuam kev zoo dua hauv cov tsev qiv ntawv tus qauv, siv lub tswv yim ntawm cov ntaub ntawv tsis hloov pauv thiab hloov pauv los ntawm lub neej ntawd, thiab muaj kev ntaus ntawv zoo li qub kom txo qis qhov yuam kev.
Main innovations:
- Rau async functions nrog rau yav tom ntej:: Tso zis, tam sim no muaj peev xwm hais kom meej "#[must_use]" annotations uas muaj cov lus ceeb toom yog tias tus nqi rov qab tsis quav ntsej, uas pab txheeb xyuas qhov tsis raug tshwm sim los ntawm kev xav tias lub luag haujlwm yuav hloov cov nqi. es tsis rov qab tus nqi tshiab. #[must_use] async fn bar() -> u32 { 0 } async fn caller() {bar().await; } ceeb toom: unused output ntawm lub neej yav tom ntej xa los ntawm `bar` uas yuav tsum tau siv β> src/lib.rs:5:5 | 5 | bar() tos; | ^^^^^^^^^^^| = note: `#[warn(unused_must_use)]` nyob ntawm lub neej ntawd
- Kev siv FIFO queues std::sync::mpsc (multi-producer single-consumer) tau hloov kho, uas tau hloov mus rau kev siv crossbeam-channel module thaum tswj hwm API dhau los. Qhov kev siv tshiab yog qhov txawv los ntawm kev daws teeb meem ntau, kev ua haujlwm siab dua thiab kev saib xyuas cov cai yooj yim.
- Ib feem tshiab ntawm API tau raug hloov mus rau qeb ntawm qhov ruaj khov, suav nrog cov txheej txheem thiab kev siv ntawm cov yam ntxwv tau ruaj khov:
- {integer}::checked_ilog
- {integer}::checked_ilog2
- {integer}::checked_ilog10
- {integer}::ilog
- {integer}::ilog2
- {integer}::ilog10
- NonZeroU*::ilog2
- NonZeroU*::ilog10
- NonZero*::BTS
- Tus cwj pwm "const", uas txiav txim siab qhov muaj peev xwm ntawm kev siv nws nyob rau hauv ib qho ntsiab lus es tsis txhob tas mus li, yog siv rau hauv kev ua haujlwm:
- char:: los ntawm_u32
- char:: los ntawm_digit
- char::to_digit
- core::char::from_u32
- core::char::from_digit
- Ib qib thib peb ntawm kev txhawb nqa tau ua tiav rau kev siv Rust hauv Linux ntsiav (linuxkernel), nrog rau Sony PlayStation 1 (mipsel-sony-psx), PowerPC nrog AIX (powerpc64-ibm-aix), QNX Neutrino RTOS ( aarch64-unknown-nto-) platforms qnx710, x86_64-pc-nto-qnx710). Qib thib peb suav nrog kev txhawb nqa yooj yim, tab sis tsis muaj kev sim siab, kev tshaj tawm ntawm kev tsim, thiab kev txheeb xyuas cov cai tsim tau.
Tsis tas li ntawd, peb tuaj yeem nco ntsoov cov ntawv tshaj tawm los ntawm ARM ntawm thaj ua rau thaj uas tso cai rau kev siv cov lus Rust los tsim cov tsav tsheb thiab Linux ntsiav modules sib sau ua ke rau cov tshuab raws li AArch64 architecture.
