Enum Sink 

pub enum Sink {
    Stderr,
    Null,
}

Where the wrapped update’s standard output (fd 1) is sent while it runs.

The redirect is applied at the file-descriptor level and therefore also captures output from child processes and native libraries, not just the current process’s buffered stdout.

Named Sink rather than “target” to avoid colliding with ReleaseUpdate::target, which reports the platform target triple.

Variants

Stderr

Fold stdout into the process’s standard error (fd 2).

Output is preserved as out-of-band diagnostics. This is the default.

Null

Discard stdout entirely, redirecting it to the /dev/null device on Unix or the NUL device on Windows.

Use this for a truly hidden update whose output should vanish.

Trait Implementations

impl Clone for Sink

fn clone(&self) -> Sink

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sink

impl Debug for Sink

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

Formats the value using the given formatter.

impl Default for Sink

fn default() -> Sink

Returns the “default value” for a type.

impl Eq for Sink

impl PartialEq for Sink

fn eq(&self, other: &Sink) -> 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.
