Struct Value 

pub struct Value<T> { /* private fields */ }

Implementations

impl<T: Send + Sync + 'static> Value<T>

pub fn new() -> Self

pub fn new_arc() -> Arc<Self>

pub fn write(&self, item: T)

pub fn write_and_tick(&self, item: T)

pub fn write_if_changed(&self, item: T)

where T: PartialEq,

pub fn write_if_changed_and_tick(&self, item: T)

where T: PartialEq,

pub fn read(&self) -> Option<T>

where T: Clone,

Read a value if changed.

pub fn force_read(&self) -> Option<T>

where T: Clone,

Read and ignore change detection, this always reads a value if initialized.

pub fn read_async(&self) -> impl FusedFuture<Output = T> + Unpin + '_

where T: Clone,

Read a value once changed asynchronously.

pub fn read_async_owned( self, ) -> impl FusedFuture<Output = (T, Self)> + Unpin + 'static

where T: Clone,

Read a value once changed asynchronously.

pub fn read_async_arc( self: Arc<Self>, ) -> impl FusedFuture<Output = T> + Unpin + 'static

where T: Clone,

Read a value once changed asynchronously.

pub fn make_readable(&self)

Rewind the tick to make the underlying value readable.

pub fn clone_uninit(&self) -> Self

Clone and duplicate the read tick, this makes the current value unreadable.

pub fn clone_init(&self) -> Self

Clone and decrement the read tick, this makes the current value always readable.

pub fn clone_raw(&self) -> Self

The real Clone implementation that does not guarantee value is readable.

Clone is not implemented since we primarily want to use Arc::clone with this type.

pub fn into_arc(self) -> Arc<Self>

Convert into Arc<Value<T>>.

pub fn to_stream(&self) -> impl FusedStream<Item = T> + Unpin + '_

where T: Clone,

pub fn into_stream(self) -> impl FusedStream<Item = T> + Unpin

where T: Clone,

pub fn into_stream_arc(self: Arc<Self>) -> impl FusedStream<Item = T> + Unpin

where T: Clone,

Trait Implementations

impl<T: Debug> Debug for Value<T>

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

Formats the value using the given formatter.

impl<T: Send + Sync + 'static> Default for Value<T>

fn default() -> Self

Returns the “default value” for a type.
