3.2.2.3. Context Lambdas

Dynamic-sized structs are supported by this library through the use of so-called context lambdas. The library introduces a special callable, _ContextLambda, which accepts a _ContextLike instance and returns the desired result.

To implement a context lambda, a class must define the __call__() method.

object.__call__(self, context)

The library does not distinguish between general callable objects and context lambdas; both are treated as instances of the same class.

Derived Protocols

class _ContextLambda[_RT]

__call__(self, context: _ContextLike) → _RT
