• tee file.txt, or
• wc -l > out.txt inside cat < in.txt | tee file.txt | wc -l > out.txt &.

Implementations

impl BasicCmd

pub fn executable(&self) -> &str

Getter for executable.

pub fn args(&self) -> &Vec<String>

Getter for args.

pub fn in_red_path(&self) -> &Option<String>

Getter for in_red_path.

pub fn out_red_path(&self) -> &Option<String>

Getter for in_red_path.

pub fn is_first(&self) -> bool

Getter for is_first.

pub fn is_last(&self) -> bool

Getter for is_last.

pub fn is_in_middle(&self) -> bool

Getter for is_in_middle.

pub fn args_to_c_argv(&self) -> *const *const c_char

Constructs the null-terminated argv-array on the heap. Memory must be freed theoretically in order to have proper memory management but because the address space content is replaced after "exec()" you don't have to free it in case of successful exec().

pub fn executable_cstring(&self) -> CString

Constructs a CString for executable.

pub fn out_red_path_cstring(&self) -> Option<CString>

Constructs a CString for out_red_path.

pub fn in_red_path_cstring(&self) -> Option<CString>

Constructs a CString for in_red_path.

Trait Implementations

impl Builder<BasicCmd> for BasicCmdBuilder

fn build(self) -> BasicCmd

Builds a BasicCmd-object, if self is valid.

impl Debug for BasicCmd

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

Formats the value using the given formatter.
