Overview

Package defaults contains schema default value interfaces and request/response implementations. These default value interfaces are used by resource/schema and internally in the framework. Refer to the typed default packages, such as stringdefault, for framework-defined default values that can be used in provider-defined schemas.

Each attr.Type has a corresponding {TYPE} interface which implements concretely typed Default{TYPE} methods, such as StringDefault and DefaultString.

The framework has to choose between default value developers handling a concrete framework value type, such as types.Bool, or the framework interface for custom value basetypes, such as basetypes.BoolValuable.

In the framework type model, the developer can immediately use the value. If the value was associated with a custom type and using the custom value type is desired, the developer must use the type's ValueFrom{TYPE} method.

In the custom type model, the developer must always convert to a concrete type before using the value unless checking for null or unknown. Since any custom type may be passed due to the schema, it is possible, if not likely, that unknown concrete types will be passed to the default.

The framework chooses to pass the framework value type. This prevents the potential for unexpected runtime panics and simplifies development for easier use cases where the framework type is sufficient. More advanced developers can choose to call the type's ValueFrom{TYPE} method to get the desired custom type in a plan modifier.

Defaults that are not type dependent need to implement all interfaces, but can use shared logic to reduce implementation code.
