Struct QrexecClient 

pub struct QrexecClient {
    pub child: Child,
    pub read: ChildStdout,
    pub written: ChildStdin,
    pub stderr: ChildStderr,
}

BUF_LEN is the size of the buffer used with the qrexec-client-vm call, –buffer-size=BUF_LEN, argument, and the size of the buffer used to write into the qrexec-client-vm file descriptors behind the scenes. The only thing you need to know when you set this is that 8 extra bytes are taken up by the header therefore you cannot send more data than <BUF_LEN - 8> in a single write call.

Fields

child: Child

read: ChildStdout

written: ChildStdin

stderr: ChildStderr

Implementations

impl QrexecClient

pub fn new<const BUF_LEN: usize>( target_vmname: &str, rpc_service: &str, local_program: Option<&str>, local_program_args: Option<&[&str]>, ) -> QRXRes<Self>

Calls qrexec-client-vm with the arguments provided through the args parameter. Arguments:

target_vmname: self explanatory

rpc_service: the service you are calling on the target vm, this can include an argument for the service using this syntax: some.service+argument.

local_program: Full path to local program to be connected with remote service.

local_program_args: Arguments for the local program.

Trait Implementations

impl Debug for QrexecClient

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

Formats the value using the given formatter.

impl Drop for QrexecClient

fn drop(&mut self)

Executes the destructor for this type.

impl QIO for QrexecClient

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

returns the number of bytes read into the buffer

fn write(&mut self, buf: &[u8]) -> Result<usize>

returns the number of bytes written from the buffer. You cannot send more data than BUF_LEN - 8 in a single call to this function as this would result in an
overflow.
