Struct Redirects

pub struct Redirects { /* private fields */ }

Contains a stack or redirects that can be processed in order to setup the file descriptors for a new process.

Implementations

impl Redirects

pub fn new() -> Self

Create a new empty redirect stack.

pub fn process(&self, jobs: &mut Jobs) -> Result<HashSet<FileDesc>, Error>

Process the stack in order and setup all the requested file descriptors. Returns a Set containing all the file descriptors setup (to avoid closing them on process start).

pub fn set_in_internal_fd( &mut self, dest_fd: FileDesc, source_fd: FileDesc, push_back: bool, )

Push a fd to fd redirect onto the stack. This is for internally managed source FDs (for pipes etc). If push_back is true then push to the end else put on the front (useful for pipes).

pub fn set_out_internal_fd( &mut self, dest_fd: FileDesc, source_fd: FileDesc, push_back: bool, )

Push a fd to fd redirect onto the stack. This is for internally managed source FDs (for pipes etc). If push_back is true then push to the end else put on the front (useful for pipes).

pub fn set_in_fd(&mut self, dest_fd: FileDesc, source_fd: Arg, push_back: bool)

Push a fd to fd redirect onto the stack. If push_back is true then push to the end else put on the front (useful for pipes).

pub fn set_out_fd(&mut self, dest_fd: FileDesc, source_fd: Arg, push_back: bool)

Push a fd to fd redirect onto the stack. If push_back is true then push to the end else put on the front (useful for pipes).

pub fn set_in_out_fd(&mut self, dest_fd: FileDesc, source_fd: Arg)

Push a fd to fd redirect onto the stack.

pub fn set_in_out_path(&mut self, dest_fd: FileDesc, path: Arg)

Push an input file path to the redirect stack for fd.

pub fn set_in_path(&mut self, dest_fd: FileDesc, path: Arg)

Push an input file path to the redirect stack for fd.

pub fn set_in_direct(&mut self, dest_fd: FileDesc, data: Arg)

Push input data to the redirect stack for fd.

pub fn set_out_path(&mut self, dest_fd: FileDesc, path: Arg, overwrite: bool)

Push an output file path to the redirect stack for fd.

pub fn clear(&mut self)

Clear the redirect stack.

pub fn extend(&mut self, other: &Redirects)

Extend this redir stack with the redirs from other.
