* use dyn Trait syntax where appropriate recent rust nightly started warning that not using `dyn` was deprecated. This requires MSRV 1.27.0+. * rustfmt fallout from dyn additions * stop explicit allow of rust_2018_idioms * more dyn Trait syntax * drop tokio-macros from 0.1.x workspace Since tokio-macros specifies an edition=2018, we would otherwise require MSRV 1.31.0 to build/test it. And tokio-macros isn't used with tokio 0.1.x. * reactor: narrow tokio-io-pool dev dep to 0.1.4 Since 0.1.5-6 is now a edition=2018 crate, which has effective MSRV 1.31.0. * narrow tempfile dev-dep to avoid MSRV bump tempfile 3.1.0 pulls in rand 0.7.0 and is MSRV 1.32.0 * narrow flate2 dev-dep to avoid MSRV bump flate2 1.0.10-11 have MSRV 1.34.0. github refs: alexcrichton/flate2-rs#207 * fs: drop deprecated tempdir crate use in tests In particular because it pulls in old rand duplicates. Replace use with tempfile::tempdir() which has been available since tempfile 3.0.0. backport-of: #1312 * increase CI MSRV to 1.28.0
tokio-executor
Task execution related traits and utilities.
Overview
In the Tokio execution model, futures are lazy. When a future is created, no work is performed. In order for the work defined by the future to happen, the future must be submitted to an executor. A future that is submitted to an executor is called a "task".
The executor is responsible for ensuring that [Future::poll] is called
whenever the task is [notified]. Notification happens when the internal state of
a task transitions from "not ready" to ready. For example, a socket might have
received data and a call to read will now be able to succeed.
This crate provides traits and utilities that are necessary for building an executor, including:
-
The
Executortrait describes the API for spawning a future onto an executor. -
entermarks that the current thread is entering an execution context. This prevents a second executor from accidentally starting from within the context of one that is already running. -
DefaultExecutorspawns tasks onto the default executor for the current context. -
Parkabstracts over blocking and unblocking the current thread.
