Struct slog_atomic::AtomicSwitch

pub struct AtomicSwitch<O = (), E = Never>(_);

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

impl<O: Clone, E: Clone> Clone for AtomicSwitch<O, E>

fn clone(&self) -> AtomicSwitch<O, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for AtomicSwitch<(), Never>

fn default() -> Self

Returns the “default value” for a type.

impl<O, E> Drain for AtomicSwitch<O, E>

type Ok = O

Type returned by this drain

type Err = E
