Is your feature request related to a problem?

While setting the target interface's ip should work in most cases, it's possible that multiple devices have the same ip.

Also i'm having trouble using a wireguard vpn when i set Table=off. Table=off disables setting up the routes for the vpn and it justs shows up as a regular device. The connection is fine as pycurl can access it when i set

after #1121 is merged we can blame at a specific file revision.

this can be used to open the file blame at the right revision from the commit-details view.

Add a note on the TestClient section about the behavior difference between those two ways, i.e. lifespan events.

Considering the follow application:

from starlette.applications import Starlette
from starlette.requests import Request
from starlette.responses import Response
from starlette.routing import Route
from starlette.testclient import TestClient


async def startup() 

While network maintenance was being performed the following error popped-up:

 thread 'main' panicked at 
'called `Option::unwrap()` on a `None` value': 
...../sqlx-core-0.5.13/src/postgres/listener.rs:165

Unfortunately I was unable to reproduce this issue in a lab environment. Looking at the code however, I would imagine the culprit is:

What should happen if deliver_cancel raises an exception? In the current implementation, the shielded cancel scope will prevent it from propagating until the process exits, which might take a while if the crash occurred before signaling the process in any way. Maybe on exception from a user-specified deliver_cancel we should call the default deliver_cancel to kill the process? Or just kill() since

Stitching API

Opencv provide a Stitching module/API

Bascially, i would like to be able to rewrite stitching_detailed.cpp in javascript

This includes :

• Stitcher class
• Features extractors (already implemented in opencv4nodejs)
• Estimator
