The selected version of concurrent-queue is incorrect in the Cargo.toml and should be at least 2.5 since #89 .
async-channel version 2.3.0 use ForcePushError which is only available since concurrent-queue version 2.5.0.
Thus, if you have any version prior to 2.5.0 in your Cargo.lock, it will not compile. (This actually fails only if you have a version of concurrent-queue previously set to 2.4.0, the others versions are not compatible with event-listener, which is used by concurrent-queue).
Simple steps to reproduce the error:
cargo new ac-bug
cd ac-bug
cargo add async-channel@2.3.0
# Everything works fine because `cargo` will pull the last version of `concurrent-queue` with 2.x.y.
cargo b
# This is valid because `concurrent-queue` should be `^2.4.0` thanks to `event-listener`.
cargo update concurrent-queue --precise 2.4.0
# Note: This will be rejected
cargo update concurrent-queue --precise 2.3.0
# Kaboom
cargo b
