Expand description

Extension to add file descriptor mappings to a Command.

Required methods

fn fd_mappings(
    &mut self,
    mappings: Vec<FdMapping>
) -> Result<&mut Self, FdMappingCollision>[src]

Adds the given set of file descriptors to the command.

Warning: Calling this more than once on the same command, or attempting to run the same command more than once after calling this, may result in unexpected behaviour.

fn preserved_fds(&mut self, fds: Vec<RawFd>) -> &mut Self[src]

Adds the given set of file descriptors to be passed on to the child process when the command is run.
