| all). | |
| -l [<KIND>[:<MODIFIERS>]=]<NAME>[:<RENAME>] | |
| Link the generated crate(s) to the specified native | |
| library NAME. The optional KIND can be one of | |
| <static|framework|dylib> (default: dylib). | |
| Optional comma separated MODIFIERS | |
| <bundle|verbatim|whole-archive|as-needed> | |
| may be specified each with a prefix of either '+' to | |
| enable or '-' to disable. | |
| --crate-type <bin|lib|rlib|dylib|cdylib|staticlib|proc-macro> | |
| Comma separated list of types of crates | |
| for the compiler to emit | |
| --crate-name <NAME> | |
| Specify the name of the crate being built | |
| --edition <2015|2018|2021|2024|future> | |

| compiling code. The default is 2015 and the latest | |
| stable edition is 2024. | |
| --emit <TYPE>[=<FILE>] | |
| Comma separated list of types of output for the | |
| compiler to emit. | |
| Each TYPE has the default FILE name: | |
| * asm - CRATE_NAME.s | |
| * llvm-bc - CRATE_NAME.bc | |
| * dep-info - CRATE_NAME.d | |
| * link - (platform and crate-type dependent) | |
| * llvm-ir - CRATE_NAME.ll | |
| * metadata - libCRATE_NAME.rmeta | |
| * mir - CRATE_NAME.mir | |
| * obj - CRATE_NAME.o | |
| * thin-link-bitcode - CRATE_NAME.indexing.o | |
| --print <INFO>[=<FILE>] | |
| Compiler information to print on stdout (or to a file) | |
| INFO may be one of | |
| <all-target-specs-json|backend-has-zstd|calling-conventions|cfg|check-cfg|code-models|crate-name|crate-root-lint-levels|deployment-target|file-names|host-tuple|link-args|native-static-libs|relocation-models|split-debuginfo|stack-protector-strategies|supported-crate-types|sysroot|target-cpus|target-features|target-libdir|target-list|target-spec-json|target-spec-json-schema|tls-models>. | |
| -g Equivalent to -C debuginfo=2 | |
| -O Equivalent to -C opt-level=3 | |
| -o <FILENAME> Write output to FILENAME | |
| --out-dir <DIR> Write output to compiler-chosen filename in DIR | |
| --explain <OPT> Provide a detailed explanation of an error message | |
| --test Build a test harness | |
| --target <TARGET> | |
| Target tuple for which the code is compiled | |
| -A, --allow <LINT> Set lint allowed | |
| -W, --warn <LINT> Set lint warnings | |
| --force-warn <LINT> | |
| Set lint force-warn | |
| -D, --deny <LINT> Set lint denied | |
| -F, --forbid <LINT> Set lint forbidden | |
| --cap-lints <LEVEL> | |
| Set the most restrictive lint level. More restrictive | |
| lints are capped at this level | |
| -C, --codegen <OPT>[=<VALUE>] | |
| Set a codegen option | |
| -V, --version Print version info and exit | |
| -v, --verbose Use verbose output | |
| Additional help: | |
| -C help Print codegen options | |
| -W help Print 'lint' options and default settings | |
| -Z help Print unstable compiler options | |
| --help -v Print the full set of options rustc accepts | |
