Enum RedirectKind

pub enum RedirectKind<W> {
    Read(Option<u16>, W),
    Write(Option<u16>, W),
    ReadWrite(Option<u16>, W),
    Append(Option<u16>, W),

}

Represents redirecting a command’s file descriptors.

Variants

Read(Option<u16>, W)

Open a file for reading, e.g. [n]< file.

Write(Option<u16>, W)

Open a file for writing after truncating, e.g. [n]> file.

ReadWrite(Option<u16>, W)

Open a file for reading and writing, e.g. [n]<> file.

Append(Option<u16>, W)

Open a file for writing, appending to the end, e.g. [n]>> file.

Clobber(Option<u16>, W)

Open a file for writing, failing if the noclobber shell option is set, e.g. [n]>| file.

Heredoc(Option<u16>, W)

Lines contained in the source that should be provided by as input to a file descriptor.

DupRead(Option<u16>, W)

Duplicate a file descriptor for reading, e.g. [n]<& [n|-].

DupWrite(Option<u16>, W)

Duplicate a file descriptor for writing, e.g. [n]>& [n|-].

Trait Implementations

impl<W: Clone> Clone for RedirectKind<W>

fn clone(&self) -> RedirectKind<W>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Debug> Debug for RedirectKind<W>

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

Formats the value using the given formatter.

impl<W: PartialEq> PartialEq for RedirectKind<W>

fn eq(&self, other: &RedirectKind<W>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
