- final type ContextLifeCycleScope = LifeCycleScope[ContextLifeCycleScopeDiscriminator]
The type for LifeCycleScopes that have accumulated all LifeCycleManagers up to the caller of the most recent call into this HasLifeCycleScope instance.
The type for LifeCycleScopes that have accumulated all LifeCycleManagers up to the caller of the most recent call into this HasLifeCycleScope instance. It may not contain the manager of this instance.
Public methods should take this kind of LifeCycleScope.

OwnLifeCycleScope
- abstract type ContextLifeCycleScopeDiscriminator >: ContextLifeCycleScopeDiscriminatorLower <: ContextLifeCycleScopeDiscriminatorUpper
The discriminator that binds a context's LifeCycleScopes to an individual instance of HasLifeCycleScope.
The discriminator that binds a context's LifeCycleScopes to an individual instance of HasLifeCycleScope. It is deliberately left unspecified so that scalac cannot derive type equalities for the discriminator across different instances of HasLifeCycleScope.
The abstract upper bounds here and on OwnLifeCycleScopeDiscriminator ensure that we can distinguish ContextLifeCycleScopes from OwnLifeCycleScopes in implicit conversions such as augmentContextLifeCycleScope.
The upper and lower bounds together ensure that implementations cannot refine this type and OwnLifeCycleScopeDiscriminator so that scalac could derive a type equality between them. For without either of the bounds, scala.Any or scala.Nothing would be valid refinements.
- final type OwnLifeCycleScope = LifeCycleScope[OwnLifeCycleScopeDiscriminator]
The type for LifeCycleScopes that have accumulated all LifeCycleManagers up to and including this HasLifeCycleScope instance.
The type for LifeCycleScopes that have accumulated all LifeCycleManagers up to and including this HasLifeCycleScope instance.
Private and protected methods should take this kind of LifeCycleScope if they are meant to be called only from the same instance.
protectedbecause it rarely makes sense to use this type outside of this instance; other call sites have a hard time to ensure that this instance's LifeCycleManager has already been accumulated.Instances can only be produced by augmentOwnLifeCycleScope.

ContextLifeCycleScope
- abstract type OwnLifeCycleScopeDiscriminator >: OwnLifeCycleScopeDiscriminatorLower <: OwnLifeCycleScopeDiscriminatorUpper
The discriminator for an individual instance's own LifeCycleScope.
The discriminator for an individual instance's own LifeCycleScope. It is deliberately left unspecified so that scalac cannot derive type equalities for the discriminator across different instances of HasLifeCycleScope.
The abstract upper bounds here and on ContextLifeCycleScopeDiscriminator ensure that we can distinguish ContextLifeCycleScopes from OwnLifeCycleScopes in implicit conversions such as augmentOwnLifeCycleScope.
The upper and lower bounds together ensure that implementations cannot refine this type and OwnLifeCycleScopeDiscriminator so that scalac could derive a type equality between them. For without either of the bounds, scala.Any or scala.Nothing would be valid refinements.

- implicit abstract def augmentContextLifeCycleScope[A >: ContextLifeCycleScopeDiscriminatorLower <: ContextLifeCycleScopeDiscriminatorUpper](implicit scope: ContextLifeCycleScope): LifeCycleScope[A]
Converts a ContextLifeCycleScope from this instance into a ContextLifeCycleScope of another instance of HasLifeCycleScope, possibly adding this HasLifeCycleScope's manager to the scope.
Converts a ContextLifeCycleScope from this instance into a ContextLifeCycleScope of another instance of HasLifeCycleScope, possibly adding this HasLifeCycleScope's manager to the scope.
- A
The HasLifeCycleScope.ContextLifeCycleScopeDiscriminator of the other instance. We cannot directly constrain to
A <: HasLifeCycleScopebecause this would break implicit resolution in scalac. Instead, we use the bounds to ensure that the returned LifeCycleScope can only be used as a ContextLifeCycleScope. In particular, we must forbid that this method returns a scope of type HasLifeCycleScope.OwnLifeCycleScope for another instance of HasLifeCycleScope.
