"""Trio - A friendly Python library for async concurrency and I/O
|
|
"""
|
|
|
|
# General layout:
|
|
#
|
|
# trio/_core/... is the self-contained core library. It does various
|
|
# shenanigans to export a consistent "core API", but parts of the core API are
|
|
# too low-level to be recommended for regular use.
|
|
#
|
|
# trio/*.py define a set of more usable tools on top of this. They import from
|
|
# trio._core and from each other.
|
|
#
|
|
# This file pulls together the friendly public API, by re-exporting the more
|
|
# innocuous bits of the _core API + the higher-level tools from trio/*.py.
