future incompatibility of redis v0.20

[calebdiaz]

the following packages contain code that will be rejected by a future version of Rust: redis v0.20

Dependencies of r2d2-redis:

[dependencies]
r2d2 = "0.8"
redis = "0.20.0"

[surfingtomchen]

can we just upgrade the redis version to "0.23"?

This crate is essentially unmaintained.
the redis crate comes with a r2d2 feature now, which should replace usage of r2d2-redis, see redis-rs/redis-rs#385 (comment)

I'll see to mark this repo as unmaintained.
