Fields

cmd: Command

Implementations

impl LlvmFilecheck

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

where K: AsRef<OsStr>, V: AsRef<OsStr>,

Specify an environment variable.

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

where K: AsRef<OsStr>,

Remove an environmental variable.

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.

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.

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.

pub fn run(&mut self) -> CompletedProcess

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

pub fn run_fail(&mut self) -> CompletedProcess

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

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.

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

Set the path where the command will be run.

impl LlvmFilecheck

pub fn new() -> Self

Construct a new llvm-filecheck invocation. This assumes that llvm-filecheck is available at $LLVM_FILECHECK.

pub fn stdin<I: AsRef<[u8]>>(&mut self, input: I) -> &mut Self

Pipe a read file into standard input containing patterns that will be matched against the .patterns(path) call.

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

Provide the patterns that need to be matched.

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

--input-file option.

Trait Implementations

impl Debug for LlvmFilecheck

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
