Struct Value 

Source 
pub struct Value<T>(/* private fields */);
👎Deprecated: It is probably a bad idea to use this crate
Expand description

A value that may eventually resolve.

Implementations§

Source§

impl<T> Value<T>

Source

pub fn immediate(val: T) -> Self

👎Deprecated: It is probably a bad idea to use this crate

Create a Value that is already resolved.

This is useful in code where once branch may need to use the driving thread, but another can be resolved immediately.

Source

pub fn is_resolved(&self) -> bool

👎Deprecated: It is probably a bad idea to use this crate
Source

pub fn resolve(self) -> Result<T, Value<T>>

👎Deprecated: It is probably a bad idea to use this crate

Try to resolve the value immediately.

Source

pub fn wait(self) -> T

👎Deprecated: It is probably a bad idea to use this crate

Wait for the value to be resolved.
