Annotations
@FunctionalInterface
Type Parameters
<T>
the scalar value type held by the implementing reactive type
Imports
io.reactivex.rxjava3.annotations.NonNull, io.reactivex.rxjava3.functions.Supplier
A marker interface indicating that a scalar, constant value is held by the implementing reactive type which can be safely extracted during assembly time can be used for optimization.

Implementors of get() should not throw any exception.

Design Note

the interface extends Supplier because if a scalar is safe to extract during assembly time, it is also safe to extract at subscription time or later. This allows optimizations to deal with such single-element sources uniformly.
