Expand description

A platform-specific C compiler invocation builder. The specific C compiler used is passed down from compiletest.

Implementations§

source§

impl Cc

source

pub fn env<K, V>(&mut self, key: K, value: V) -> &mut Self
where K: AsRef<OsStr>, V: AsRef<OsStr>,

Specify an environment variable.

source

pub fn env_remove<K>(&mut self, key: K) -> &mut Self
where K: AsRef<OsStr>,

Remove an environmental variable.

source

pub fn arg<S>(&mut self, arg: S) -> &mut Self
where S: AsRef<OsStr>,

Generic command argument provider. Prefer specific helper methods if possible. Note that for some executables, arguments might be platform specific. For C/C++ compilers, arguments might be platform and compiler specific.

source

pub fn args<V, S>(&mut self, args: V) -> &mut Self
where V: AsRef<[S]>, S: AsRef<OsStr>,

Generic command arguments provider. Prefer specific helper methods if possible. Note that for some executables, arguments might be platform specific. For C/C++ compilers, arguments might be platform and compiler specific.

source

pub fn inspect<I>(&mut self, inspector: I) -> &mut Self
where I: FnOnce(&Command),

Inspect what the underlying Command is up to the current construction.

source

pub fn run(&mut self) -> CompletedProcess

Run the constructed command and assert that it is successfully run.

source

pub fn run_fail(&mut self) -> CompletedProcess

Run the constructed command and assert that it does not successfully run.

source

pub fn run_unchecked(&mut self) -> CompletedProcess

Run the command but do not check its exit status. Only use if you explicitly don’t care about the exit status. Prefer to use Self::run and Self::run_fail whenever possible.

source

pub fn current_dir<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Set the path where the command will be run.

source§

impl Cc

source

pub fn new() -> Self

Construct a new platform-specific C compiler invocation.

WARNING: This means that what flags are accepted by the underlying C compile is platform- AND compiler-specific. Consult the relevant docs for gcc, clang and mvsc.

source

pub fn new_cxx() -> Self

Construct a new platform-specific CXX compiler invocation. CXX_DEFAULT_FLAGS is passed from compiletest.

source

pub fn input<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Specify path of the input file.

source

pub fn library_search_path<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Adds directories to the list that the linker searches for libraries. Equivalent to -L.

source

pub fn out_exe(&mut self, name: &str) -> &mut Self

Specify -o or -Fe/-Fo depending on platform/compiler.

source

pub fn output<P: AsRef<Path>>(&mut self, path: P) -> &mut Self

Specify path of the output binary.

source

pub fn optimize(&mut self) -> &mut Self

Optimize the output. Equivalent to -O3 for GNU-compatible linkers or -O2 for MSVC linkers.

source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
