pub struct ConfigValHandle<T> {
pub(crate) val: ConfigValAtomic,
pub(crate) _type: PhantomData<T>,
}
Expand description
A handle to a configuration value in a ConfigSet
.
Allows users to amortize the lookup of a name within a set.
Handles can be cheaply cloned.

Implementations§
Source§impl<T: ConfigType> ConfigValHandle<T>
impl<T: ConfigType> ConfigValHandle<T>
Sourcepub fn get(&self) -> T
pub fn get(&self) -> T
Returns the latest value of this config within the set associated with the handle.
Sourcepub fn disconnected<X>(value: X) -> Selfwhere
X: ConfigDefault<ConfigType = T>,
pub fn disconnected<X>(value: X) -> Selfwhere
X: ConfigDefault<ConfigType = T>,
Return a new handle that returns the constant value provided, generally for testing.
