edc.ContextStack

class etils.edc.ContextStack(**kwargs)

Bases: Generic[etils.edc.stack._T]

Local stack object (per-thread and contextvars-aware).

Each thread / coroutine will have its own stack. This ensure that contextmanagers from different threads do not conflict.

Usage:

_stack = edc.ContextStack[int]()

@contextlib.contextmanager
def my_thread_safe_contextmanager():
  _stack.append(1)
  try:
    yield
  finally:
    _stack.pop()

stack: Annotated[list[etils.edc.stack._T], <object object at 0x7fcbe0f38350>]

append(value: etils.edc.stack._T) → None

Append a value to the stack.

pop() → etils.edc.stack._T

Pop the last value from the stack.

replace(

**kwargs: Any,

) → etils.edc.dataclass_utils._T

Similar to dataclasses.replace.
