Hello,
I'm having trouble simply adding this crate to my project. The cfg conditional featured-based use statements do not seem to be taken into account. Here are the errors:

error: aborting due to 12 previous errors
These errors appear whether or not I add the features = ["runtime-tokio"] to my Cargo.toml. I'm working with rustc 1.49.0 (e1884a8e3 2020-12-29) and here is the list of dependencies from my Cargo.toml:
[dependencies]
actix-casbin-auth = { version = "0.4.4", features = ["runtime-tokio"] }
actix-files = "0.5.0"
actix-redis = "0.9.1"
actix-session = "0.4.0"
actix-web = { version = "3", default-features = false }
chrono = { version = "0.4.19", features = ["serde"]}
diesel = { version = "^1.4.4", features = ["postgres","r2d2","chrono"] }
diesel-adapter = { version = "0.8.3", features = ["postgres"] }
diesel-derive-enum = { version = "1.1.0", features = ["postgres"] }
dotenv = "0.15"
env_logger = "0.7"
failure = "0.1.8"
futures = "0.3.8"
lazy_static = "1.4.0"
lettre = "0.10.0-alpha.4"
log = "0.4.13"
regex = "1.4.3"
sailfish = "0.3.0"
sailfish-macros = "0.3.0"
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
sodiumoxide = "0.2.6"
strum_macros = "0.20.1"
uuid = { version = "0.8", features = ["serde", "v4"] }
walkdir = "2.3.1"Any help would be appreciated.
@hackerchai @PsiACE plz take a look
/cc @GopherJ
@arnaudpoullet Try to write cargo.toml like this:
actix-casbin= {version = "0.4.2", default-features = false, features = [ "runtime-async-std" ]}
actix-casbin-auth = {version = "0.4.4", default-features = false, features = [ "runtime-async-std" ]}
diesel-adapter = { version = "0.8.1", default-features = false, features = ["postgres","runtime-async-std"] }This should avoid async runtime multipile importing issue.
Thank you8 This works indeed. I think this should be added to the Install section of the README.
As well, I don't want to make a new issue for this, but I had to do an extra import to get the example code working in my main. I think it should be added too, because it doesn't seem to work without.
use actix_casbin_auth::casbin::function_map::key_match2;
@arnaudpoullet can you make a PR to fix the README?
