tbot223-base

tbot223-base is a small Python base package for exchanging operation results and safe exception payloads across function and module boundaries.

It provides two core pieces:

• Result and ResultStatus for explicit success, failure, and cancelled outcomes.
• ExceptionTracker for separating internal debug diagnostics from public-safe error payloads.

Design Intent

tbot223-base was shaped by Python boundary-handling needs, not by an attempt to reproduce another language's API.

Rust's Result can be a useful comparison point for readers, but it is not the source model or compatibility target for this package. Here, Result is a Python-style exchange protocol: a small value shape that lets functions pass status, data, context, and error text without guessing how the caller wants to handle the outcome.

ExceptionTracker exists for safe error handling at boundaries. It does not make errors disappear; it keeps rich internal diagnostics available while producing a smaller public payload that avoids traceback, local variable, system, or raw exception leakage.

Who This Is For

This package fits codebases that want:

• a stable result shape for function, service, worker, or module boundaries.
• a lightweight way to return success, failure, and cancellation without inventing a new dictionary shape in each layer.
• public-safe error payloads for APIs, UI surfaces, bot responses, or other untrusted boundaries.
• debug diagnostics that can stay richer than public responses.
• a small typed utility package rather than a framework.

It is especially useful when an operation result is part of the interface between components, not just a local implementation detail.

Trade-offs

Result makes outcomes explicit, but that also means callers and callees must agree to pass and inspect a structured value. For very small scripts or code where normal exceptions are already the clearest control flow, this can be unnecessary ceremony.

ExceptionTracker intentionally separates public and debug payloads. That is safer for public boundaries, but it also means public responses will not contain raw exception messages, traceback frames, local variables, or system information unless you explicitly provide safe public text.

This package is not:

• a Rust-compatible Result implementation.
• a pattern-matching or monadic result framework.
• a logging, tracing, metrics, or observability system.
• a replacement for Python exceptions inside purely local control flow.

Installation

python -m pip install tbot223-base

For local development from a source checkout:

python -m pip install -e ".[test]"

Quickstart

Create and inspect a result.

from tbot223_base.result import Result, ResultStatus

result: Result[dict[str, int]] = Result(
    status=ResultStatus.SUCCESS,
    error=None,
    context="FetchProfile",
    data={"user_id": 1},
)

if result.is_success:
    print(result.unwrap())

Return a public-safe exception payload.

from tbot223_base.exception_tracker import ExceptionTracker

tracker = ExceptionTracker()

try:
    1 / 0
except Exception as error:
    result = tracker.get_public_exception_return(
        error,
        error_code="DIVIDE_BY_ZERO",
        public_message="The calculation could not be completed.",
        public_context="Calculator.Divide",
        retryable=False,
    )
    print(result.data)
