ProvidableCompositionLocal

infix fun provides(value: T): ProvidedValue<T>

Associates a CompositionLocal key to a value in a call to CompositionLocalProvider.

infix fun providesComputed(compute: CompositionLocalAccessorScope.() -> T): ProvidedValue<T>

Associates a CompositionLocal key to a lambda, compute, in a call to CompositionLocal. The compute lambda is invoked whenever the key is retrieved. The lambda is executed in the context of a CompositionLocalContext which allow retrieving the current values of other composition locals by calling CompositionLocalAccessorScope.currentValue, which is an extension function provided by the context for a CompositionLocal key.

infix fun providesDefault(value: T): ProvidedValue<T>

Associates a CompositionLocal key to a value in a call to CompositionLocalProvider if the key does not already have an associated value.
