Struct Guard 

pub struct Guard(/* private fields */);

The presence of a Guard delays shutdown.

Dropping all Guards in a Swansong’s subset allows the ShutdownCompletion future returned by awaiting the Swansong to complete.

Each clone is treated distinctly in the guard count.

A Guard keeps its originating node’s coordination state alive for the Guard’s lifetime, so that its drop can correctly update ancestor subtree accounting even if every Swansong handle to that node has been dropped.

Two guards are Eq if they share the same Swansong.

Trait Implementations

impl Clone for Guard

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Guard

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

Formats the value using the given formatter.

impl Drop for Guard

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for Guard

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