A highly opinionated flake8 plugin for Trio-related problems.
Project description
flake8-trio
A highly opinionated flake8 plugin for Trio-related problems.
This can include anything from outright bugs, to pointless/dead code, to likely performance issues, to minor points of idiom that might signal a misunderstanding.
It may well be too noisy for anyone with different opinions, that's OK.
Pairs well with flake8-async and flake8-bugbear.
Installation
pip install flake8-trio
List of warnings

yieldinside a nursery or cancel scope is only safe when implementing a context manager - otherwise, it breaks exception handling. - TRIO102 it's unsafe to await inside
finally:unless you use a shielded cancel scope with a timeout" - TRIO105 Calling a trio async function without immediately
awaiting it.
