Struct AtomicSwitch 

pub struct AtomicSwitch<O = (), E = Never>(/* private fields */);

Drain wrapping another drain, allowing atomic substitution in runtime.

Implementations

impl<O, E> AtomicSwitch<O, E>

pub fn new<D: SendSyncRefUnwindSafeDrain<Ok = O, Err = E> + 'static>( drain: D, ) -> Self

Wrap drain in AtomicSwitch to allow swapping it later

Use AtomicSwitch::ctrl() to get a handle to it

pub fn ctrl(&self) -> AtomicSwitchCtrl<O, E>

Get a AtomicSwitchCtrl handle to control this AtomicSwitch drain

Trait Implementations
