[Happy Eyeballs]
([RFC 8305])
## Use case
This library exists to allow connecting with
[Happy Eyeballs]
([RFC 8305])
when you
already have a list of addrinfo and not a DNS name.
The stdlib version of `loop.create_connection()`
will only work when you pass in an unresolved name which
is not a good fit when using DNS caching or resolving
names via another method such as `zeroconf`.
## Installation
Install this via pip (or your favourite package manager):
`pip install aiohappyeyeballs`
## License
[aiohappyeyeballs is licensed under the same terms as cpython itself.]
## Example usage
```python
addr_infos = await loop.getaddrinfo("example.org", 80)
socket = await start_connection(addr_infos)
socket = await start_connection(addr_infos,
local_addr_infos=local_addr_infos, happy_eyeballs_delay=0.2)
transport, protocol = await loop.create_connection(
MyProtocol, sock=socket, ...)
# Remove the first address for each family from addr_info
pop_addr_infos_interleave(addr_info, 1)
# Remove all matching address from addr_info
remove_addr_infos(addr_info, "dead::beef::")
# Convert a local_addr to local_addr_infos
local_addr_infos = addr_to_addr_infos(("127.0.0.1",0))
```
